aA$)$ You are given an unknow material with the format $A_1{B}_1{C}_4.A,B$ and $C$ represents a

single element each. The precent composition of $2$ elements are as follows:

$A=24\mathrm{.}72\%$

$B=34\mathrm{.}77\%$

i$)$ What is the percentage composition of the final element?

ii$)$ You find that the molecular mass of A and $B$ together is $94\mathrm{.}04$ amu. What is the

molar mass of the compound?

iii$)$ What is the identity of element $C?$

b$)$ A compound contains copper, nitrogen and oxygen. The compound contains $33\mathrm{.}88\%$

copper and $14\mathrm{.}94\%$ nitrogen.

i$)$ What is the empirical formula?

ii$)$ Given what you have calculated, do you think the empirical and molecular

formula would be the same? Explain.
