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
Explanation
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)
