Solution

Q.
Assume carbon burns according to following equation:

$2 C_{(s)} + O_{2 (g)} \to 2 {CO}_{(g)}$

When 12 g carbon is burnt in 48 g of oxygen, the volume of carbon monoxide produced is ______ $\times 10^{- 1}$ L at STP (Nearest Integer).

[Given: Assume CO as ideal gas, Mass of C is 12 g ${mol}^{- 1}$ , Mass of O is 16 g ${mol}^{- 1}$ and molar volume of an ideal gas at STP is 22.7 L ${mol}^{- 1}$ ] [2023]

Ans.
(227)

$2 C$    $+$ $O_{2}$ $⟶$     $2 C O$

$\frac{12}{12} (LR is C)$    $\frac{48}{32}$

$1 mole$    $1.5 mole$

$0$    $\begin{matrix} (1.5 - 0.5) \\ = 1.0 mole \end{matrix}$ $1 mole$

$Mole of CO = 1 mole$

${(V_{C O})}_{at STP} = 22.7 Lit = 227 \times 10^{- 1} Lit$
