Answer:

n = 2 moles (1 sig-fig)

Explanation:

Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...

pressure = P(atm) = 100atm

volume =V(liters) = 50L

gas constant = R = 0.08206L·atm/mol·K

temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K

PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)

∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).

Moles are the ratio of the mass and the molar mass of the substance. In a 50.0 L cylinder, 2 moles of gas are present at 100 atm and 35 degrees celsius.

An ideal gas equation states the relationship between the moles of the substance, temperature, pressure, and volume. The ideal gas equation is given as,

[tex]\rm PV = nRT[/tex]

Given,

The pressure of the gas (P) = 100.0 atm

Volume of the gas (V) = 50.0 L

Temperature (T) = 308 K

Gas constant (R) =  0.08206 L atm/mol K

Substituting values in equation moles (n) is calculated as:

[tex]\begin{aligned} \rm n&= \rm \dfrac{PV}{RT}\\\\&= \dfrac{100 \times 50}{0.08206 \times 308}\\\\&= 1.978\end{aligned}[/tex]

Therefore, 1.978 or 2 moles of gas are present.

Answer:A) H20 gas

Explanation:

Based on the property of gases, 1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.

Gases are one of the states of matter.

Gas molecules have negligible forces of attraction between them, therefore, they are always in motion.

Gases do not have a specific shape or volume, rather they fill up every available space in their container.

Of the given option, only H₂ is a gas.

Therefore,  1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.

(please mark brainiest I need for new rank)

Answer:

The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.

Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.

Answer:

hydrogen(H2) and oxygen gas(O2

Answer:

0.0125mol

Explanation:

Molarity (M) = number of moles (n) ÷ volume (V)

n = Molarity × Volume

According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:

1000mL = 1L

250mL = 250/1000

= 0.250L

n = 0.05 × 0.250

n = 0.0125

The number of moles of NaOH is 0.0125mol.

Answer and Explanation:

2 mol of Fe(OH)3 produces 1 mol of Fe2(SO4)3  then 2.1 mol of Fe(OH)3 will produce (1)/(2) x 2.01 = 1.05 mol of Fe2(SO4)3  amount of H2O = (6)/(2) * 2.01 = 6.03 mol HO2

Mass of a substance = Moles of a substance × molar mass of a substance

We have 0.94 moles of NaHCO3. The molar mass of NaHCO3 is the sum of the atomic masses of the elements comprising NaHCO3, which is approximately 84.007 g/mol.

The mass of 0.94 moles of sodium bicarbonate is therefore (0.94 moles NaHCO3)(84.007 g NaHCO3/mol NaHCO3) = 78.97 ≈ 79 grams of sodium bicarbonate.

A. "All molecules are compounds, but not all compounds are molecules"

Explanation:

An example of a compound-molecule is oxygen. The elemenal is O, because the periodic table isn't describing molecules, it's describing atoms. The molecule is O2 because it takes 2 O atoms to make a molecule of oxygen.

The primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom​'.

Explanation:

So, from this, we can conclude that the primary difference between a molecule and a compound is 'compounds must be composed of more than one type of atom​'.

Answer:

Multiply the length value by 6.68456e-9

Explanation:

The question involves converting from one unit (kilometers) to another unit (Au)

From the question;

149,598,000 km = 1 AU

1 km = x

Cross multiplying;

1  * 1 = x * 149,598,000

1 = 149,598,000x

x = 1 / 149,598,000

x = 6.68456e-9

To convert kilometer to Au; Multiply the length value by 6.68456e-9

Explanation:

The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Thus, the final temperature of the system has been 130[tex]\rm ^\circ C[/tex].
