Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

(Help would be greatly appreciated) What is the molarity of a solution made from 325.4g of AlCl3 with enough water to make 500.0mL?
1. 4.88g
2. 4.88M
3. 2.440M
4. 2.44M
Answer:
4.88 M
Explanation:
M = number moles/Volume (L)
MM AlCl3 = 133.34 g/mol
Volume = 500 mL = 0.5 L
number moles = mass/MM = 325.4/133.34 = 2.44 moles AlCl3
M = 2.44/0.5 = 4.88 M

At equilibrium at 2500K, [HCl]=0.0625M and [H2]=[Cl2]=0.00450M for the reaction H2+Cl2 ⇌ HCl.
a. Determine the balanced equation and write the equilibrium expression
b. Determine the K eq
c. Will this process favor the reactants or products at equilibrium?
Answer:
a. [tex]H_2+Cl_2 \rightleftharpoons 2HCl[/tex]
b. K = 192.9
c. Products are favored.
Explanation:
Hello!
a. In this case, according to the unbalanced chemical reaction we need to balance HCl as shown below:
[tex]H_2+Cl_2 \rightleftharpoons 2HCl[/tex]
In order to reach 2 hydrogen and chlorine atoms at both sides.
b. Here, given the concentrations at equilibrium and the following equilibrium expression, we have:
[tex]K=\frac{[HCl]^2}{[H_2][Cl_2]}[/tex]
Therefore, we plug in the data to obtain:
[tex]K=\frac{(0.0625)^2}{(0.00450)(0.00450)}\\\\K=192.9[/tex]
c. Finally, we infer that since K>>1 the forward reaction towards products is favored.

Another alloy called nichrome contains only the elements chromium and nickel how much nickel dies it have
Answer:
80 g
Explanation:
Alloy = nichrome
100 g of nichrome contains 20 g of chromium
Contains only two elements (Nickel and Chromium) hence;
Mass of Alloy = Mass of Nickel + Mass of Chromium
100 = Nickel + 20g
Nickel = 100 g - 20 g = 80 g

The chemical formula of aspirin is C9H8O4. What is the mass of 0.40 mol
of aspirin?
Answer:
[tex]\boxed {\boxed {\sf About \ 72 \ grams }}[/tex]
Explanation:
To convert from moles to grams, we must use the molar mass (also known as the gram formula mass).
First, look up the molar masses of the elements in the formula.
C: 12.011 g/mol H: 1.008 g/mol O: 15.999 g/molNext, multiply by the subscript, because it tells us the number of atoms of each element in the formula.
C₉: 4(12.011 g/mol)= 108.099 g/mol H₈: 8(1.008 g/mol)= 8.064 g/mol O₄: 4(15.999 g/mol)= 63.996 g/molAdd the values.
108.099 + 8.064+63.996=180.159 g/molUse this molar mass as a ratio.
[tex]\frac {180.159 \ g \ C_9H_8O_4}{1 \ mol \ C_9H_8O_4}[/tex]
Multiply by the given number of moles, 0.40
[tex]0.40 \ mol \ C_9H_8O_4 *\frac {180.159 \ g \ C_9H_8O_4}{1 \ mol \ C_9H_8O_4}[/tex]
The units moles of aspirin cancel.
[tex]0.40 *\frac {180.159 \ g \ C_9H_8O_4}{1 }[/tex]
[tex]72.0636 \ g \ C_9H_8O_4[/tex]
The original number of moles has 2 sig figs (4 and 0), so answer must have the same. For the number we calculated, it is the ones place. The 0 in the tenth place tells us to leave the 2.
