The number of moles of methane required to produce $11 \mathrm{~g} \mathrm{CO}_{2}(\mathrm{~g})$ after complete combustion is: (Given molar mass of methane in $\mathrm{g} \mathrm{mol}^{-1}: 16$)

JEE Main · 2024 · 05 Apr 2024 · Shift 2 · Some Basic Concepts of Chemistry

The number of moles of methane required to produce

11 g CO_{2} (g)

after complete combustion is:
(Given molar mass of methane in

g mol^{- 1} : 16

)

Answer: (B)

C H_{4} + 2 O_{2} \to C O_{2} + 2 H_{2} O

: one mole of

C H_{4}

gives one mole of

C O_{2}

(44 g).
Moles of

C O_{2}

required

= \frac{11}{44} = 0.25

mol, so 0.25 mol of

C H_{4}

is needed.
