In an auto engine with no pollution controls, about 5% of the fuel `(C_8H_18)` remains unburnt. Molar ratio of `CO_2` and `C_8 H_18` emitted in the exhaust gas is

A

100

B

152

C

50

D

5

Text Solution

Verified by Experts

The correct Answer is:
B
Out of 100 mole of `C_(8)H_(18) 95` moles of `C_(8)H_(18)` burn to give `95 xx 8` mol of `CO_(2)` and 5 mol of `C_(8)H_(18)` remain unburnt.
Molar ratio in exhaust gases
`CO_(2) : C_(8)H_(18)`
`95 xx 8 : 5`
`152 : 5`
