Number of moles of methane required to produce 22 g CO 2 ( g ) after combustion is x × 10 – 2 moles. The value of x is

Correct answer

Step-by-step solution

CH 4 + 2 O 2 → CO 2 + 2 H 2 O Gram molecular mass of CO 2 = 12 + 2 ( 16 ) = 44 g / mol From the reaction, it is clear that 1 mole of methane on complete combustion produces 44 g ( 1 mole) of carbon dioxide. Therefore moles of CH 4 required to produce 22 g of CO 2 are: = 1 44 × 22 = 0 . 5 mol = 50 × 10 - 2 mol Hence, m = 50
