Question

At $STP$, how much space (in Litres) will 0.750 moles of argon gas occupy?

• A. 29.9 $L$
• B. 14.3 $L$
• C. 0.033 $L$
• D. 16.8 $L$

Answer 1

The correct option is D 16.8 $L$

At $STP$, 1 mole of $Ar$ will occupy 22.4 $L$. Hence, 0.750 moles of $Ar$ will occupy a volume of $0.750\times 22.4=16.8L$
