Question

What is the volume occupied by 0.25 moles of $N{H}_3$ gas at STP?

• A. $11200\text{mL}$
• B. $8590\text{mL}$
• C. $5600\text{mL}$
• D. $22400\text{mL}$

Answer 1

The correct option is C $5600\text{mL}$

1 mole of $N{H}_3$ gas occupies $22400\text{mL}$ at STP.
0.25 mole of the gas will occupy $\frac{22400}{1}\times 0.25\text{mL}=5600\text{mL}$
