Answer 1

At STP, the least volume will be occupied by 15g of i)NH3

Answer 2

ii) $O_{2}$

Explanation:

• At STP the volume occupied by 15g $O_{2}$
• = > (15/32) x 22.4 = 10.5 lt

• At STP the volume occupied by 15g $NH_{3}$

       = > (15/17) x 22.4 = 19.76 lt

• At STP the volume occupied by 15g $H_{2}$

        = > (15/2) x 22.4 = 168 lt

• At STP the volume occupied by 15g $H_{2}$

        = > (15/4) x 22.4 = 84 lt

Hence, At STP, the least volume will be occupied by 15g $O_{2}$.
