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 is A

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

    C       :      H

0.93       :      0.07

\(\frac{0.93}{12}\)   :   \(\frac{0.07}{1}\)

0.078         :        0.07

\(\frac{0.078}{0.07}    :    \frac{0.07}{0.07}\)

\(\approxeq   1:1\)
