Answer to Question #167699 in General Chemistry for zara

Question

An organic compound is found to contain 89.94% C and 10.06% H. It has a Molar Mass of 320g/mole. What is the empirical and true formula?

Answer 1

w=n*Ar/Mr

n=w*Mr/Ar

n(C)=0.8994*320/12=24

n(H)=0.1006*320/1=32.

So, the true formula is C₂₄H₃₂, and the empirical formula is C₃H₄.
