Solution

According to the balanced chemical equation, four moles of di-nitrogen oxide forms two moles of steam.

1 mole of gas occupy 22.4 L or 22400 cm³ volume.
Volume of two moles of steam will be 2 $\times$ 22400 cm³
Volume of 4 moles of steam will be 4 $\times$ 22400 cm³
Volume of N₂O required to produce (2 $\times$ 22400) cm³ of steam = (4 $\times$ 22400) cm³
Volume of N₂O required to produce 150 cm³ of steam = $(\frac{150 \times 4 \times 22400}{2 \times 22400}) {cm}^{3} = 300 {cm}^{3}$
