Complete combustion of 0.858 g of compound X gives 2.63 g of `CO_(2)` and 1.28 g of` H_(2)`O. The lowest molecular mass X can have

A

43 g

B

86 g

C

129 g

D

172 g

Text Solution

Verified by Experts

The correct Answer is:
A
`% C=12/44xxW_(CO_(2))/Wxx100=12/44xx2.63/0.858xx100=83.6%`
`%H=2/18xxW_(H_(2)O)/Wxx100=2/18xx1.28/.858xx100=16.4 %`
