Mass of methane required to produce 22g22g of COCO after complete combustion is g. (Given Molar mass in g mol-1, C=12.0C = 12 . 0, H=1.0H = 1 . 0, O=16.0)O = 16 . 0 )

Correct answer

0

Step-by-step solution

The molecular mass of methane  is 16g/mol16g / mol.

The reaction is as follows,

CH4+2O2→CO2+2H2O{CH}_{4} + 2{O}_{2} \to {CO}_{2} + 2{H}_{2}O

Moles of CO2=massmolar mass=2244=0.5{CO}_{2} = \dfrac{\text{mass}}{\text{molar mass}} = \dfrac{22}{44} = 0 . 5

So, required moles of CH4=0.5{CH}_{4} = 0 . 5

Mass of CH4=0.5×16=8gm{\text{Mass of CH}}_{\text{4}} = 0 . 5 \times 16 = 8gm
