A compound (molar mass = 120 g ) contain...

A compound (molar mass = 120 g ) contains 40% carbon by mass. If the ration of number of H and O
atoms in the compound is 2 : 1, then number of H- atoms in one molecule of the compound is :-

A

2

B

6

C

8

D

10

Text Solution

Verified by Experts

The correct Answer is:
C
Mass of `C=120 xx (40)/(100)=48` g Suppose number of H and O atoms are 2X and x, then
`48+2x xx 1 + x xx 16=120`
18x = 72
x=4
