If a jug hold 5 gallon of water. If a gla hold 4 oz of water, how many glae can be drawn from the water jug

Answers

The water in the 5-gallon jug will fill 160 glasses.

According to the issue, a glass carries 4 ounces of water while a jug holds 5 gallons. We must convert the jug's volume from gallons to ounces and divide it by the volume of glass in order to determine how many glasses can be filled from it.

The water in the jug needs to be converted from gallons to ounces first. A gallon contains 128 ounces, hence 5 gallons of water equal 5×128 = 640 ounces.

The amount of water in the glass is then divided by the amount of water in the jug. If a glass holds four ounces, then 160 glasses can be filled from the jug, or 640 divided by four.

It's vital to note that we are converting between units in this problem using the rule that 1 gallon = 128 ounces. This conversion factor is based on the units of a gallon and an ounce, which are both common measurements.

We can simply convert gallons to ounces using this conversion factor, which enables us to perform the calculations required to get the solution.

In conclusion, by dividing the volume of the 5-gallon jug of water by the volume of glass, 160 glasses can be filled from it. To accomplish this, we must use a conversion factor to convert water measured in gallons to ounces.

10. A chemist wants to make calcium phosphate using the following reaction:
2K3PO4 (aq) + 3CaCl₂ (aq) → Cas(PO4)2 (s) + 6KCl (aq)
culu
If he has extra calcium chloride and 750.0 mL of a 1.8 M solution of potassium
phosphate, how many grams of calcium phosphate can he produce?

Answers

Answer:

So the chemist can produce 418.7 grams of calcium phosphate.

Explanation:

We can start the problem by using the balanced chemical equation for the reaction and the stoichiometry to determine the amount of calcium phosphate that can be produced.

2K3PO4 (aq) + 3CaCl2 (aq) → Ca3(PO4)2 (s) + 6KCl (aq)

From the balanced equation, we can see that for every 2 moles of potassium phosphate (K3PO4) reacted, 1 mole of calcium phosphate (Ca3(PO4)2) is produced.

We are given that the chemist has 750.0 mL of a 1.8 M solution of potassium phosphate. We can convert this information into moles by using the formula:

moles = concentration x volume

moles = 1.8 M x (750.0 mL) / 1000 mL/L = 1.35 moles

To find the number of grams of calcium phosphate that can be produced we can use the molar mass of calcium phosphate which is 310.18 g/mol

grams = moles x molar mass

grams = 1.35 x 310.18 = 418.7 grams

So the chemist can produce 418.7 grams of calcium phosphate.

As a result, the energy storage capacity is increased by three units of charge provided by ions. Rechargeable batteries made of aluminum are inexpensive and have low flammability. Because aluminum is inert, it is safe to use and simple to use in a natural setting. Since aluminum has a higher volumetric capacity than lithium, it can store more energy per unit of volume.

How many grams of sodium nitrate will be produced from 15.1 moles of silver nitrate?

Answers

1284.689 grams of sodium nitrate will be produced from 15.1 moles of silver nitrate.

How to determine grams of sodium nitrate?

To determine how many grams of sodium nitrate will be produced from 15.1 moles of silver nitrate, we need to perform a balanced equation and stoichiometry calculation.

The balanced equation for the reaction between silver nitrate and sodium chloride to form silver chloride and sodium nitrate is:

AgNO3 (aq) + NaCl (s) → AgCl (s) + NaNO3 (aq)

We know that 15.1 moles of silver nitrate will react with the stoichiometric amount of sodium chloride, which is 1 mole of sodium chloride for every 1 mole of silver nitrate.

So, we can calculate the moles of sodium nitrate that will be produced by multiplying the moles of silver nitrate by the coefficient of sodium nitrate in the balanced equation:

15.1 moles AgNO3 * 1 mole NaNO3 / 1 mole AgNO3 = 15.1 moles NaNO3

To convert the moles of sodium nitrate to grams, we can use the molar mass of sodium nitrate, which is 84.99 g/mol.

15.1 moles NaNO3 * 84.99 g/mol = 1284.689 g

So, 1284.689 grams of sodium nitrate will be produced from 15.1 moles of silver nitrate.

Mr. Rushworth was from the first struck with the beauty of Miss Bertram, and being inclined to marry, soon fancied himself in love. He was a heavy young Line man, with not more than common sense; but as there was nothing disagreeable in his figure or address, the young lady was well pleased with her conquest. Being now in her twenty-first year, Maria Bertram was beginning to think matrimony a duty; and as a marriage with Mr. Rushworth would give her the enjoyment of a larger income than her father's, as well as ensure her the house in town, which was now a prime object, it became, by the same rule of moral obligation, her evident duty to marry Mr. Rushworth if she could. Mrs. Norris was most zealous in promoting the match, by every suggestion and contrivance, likely to enhance its desirableness to either party; and, among other means, by seeking an intimacy with the gentleman's mother, who at present lived with him, and to whom she even forced Lady Bertram to go through ten miles of indifferent road, to pay a morning visit. (5)It was not long before a good understanding took place between this lady and herself. Mrs. Rushworth acknowledged herself very desirous that her son should marry, and declared that of all the young ladies she had ever seen, Miss Bertram seemed, by her amiable qualities and accomplishments, the best adapted to make him happy. Mrs. Norris accepted the compliment, and admired the nice discernment of character which could so well distinguish merit. Maria was indeed the pride and delight of them allperfectly faultlessan angel; and of course, so surrounded by admirers, must be difficult in her choice; but yet as far as Mrs. Norris could allow herself to decide on so short an acquaintance, Mr. Rushworth appeared precisely the young man to deserve and attach her. After dancing with each other at a proper number of balls, the young people justified these opinions, and an engagement, with a due reference to the absent Sir Thomas, was entered into, much to the satisfaction of their respective families, and of the general lookers-on of the neighbourhood, who had, for many weeks past, felt the expediency of Mr. Rushworth's marrying Miss Bertram.
