Analysis of a hydrocarbon shows that it contains 0.93g of Carbon per gram of the compound. The mole ratio of carbon to hydrogen in the compound is [H = 1.0, C=12.0]

A. 1:1
B. 1:2
C. 2:1
D. 2:3

Correct Answer: Option A

A. 1:1

Explanation

1g of Hydrocarbon = 0.93g of Carbon, therefore, Hydrogen = (1 – 0.93)g = 0.07g

C : H

0.93 : 0.07

0.93/12 : 0.07/1

0.078 : 0.07

0.078/0.07 : 0.07/0.07
