Answer
x = 2, y = 2
Explanation
The empirical formula is the simplest whole number ration that defines constituent atoms in a species.
The molecular formula is always a multiple of the empirical formula.
Since the empirical formula of the compound i given to be CH, ithen its molecula formula is:
[tex]Molecular\text{ }formula=n\times(empirical\text{ }formula)[/tex]From the periodic table, the molar masses of (H = 1.00784, C = 12.011)
Thus, the molecular formula is
[tex]\begin{gathered} Molecular\text{ }formula=28\text{ }g\text{/}mol=n(12.011+1.00784)\text{ }g\text{/}mol \\ \\ n=\frac{28}{12.011+1.00784}=\frac{28}{13.01884}=2.150729251\approx2 \end{gathered}[/tex](CH)n = (CH)₂ = C₂H₂
Therefore, CxHy = C₂H₂. The value of x and y is 2 and 2 respectively.
The value of x and y if its empirical formula is CH is x = 2, y = 2
