0.250 moles of $HCl$ gas occupies how many liters at STP?

• A. $6.5\text{L}$
• B. $4.2\text{L}$
• C. $5.6\text{L}$
• D. $6.2\text{L}$

Answer 1

The correct option is C $5.6\text{L}$

$\text{Volume of one mole of gas at STP}=22.4$
$\text{Volume of 0.250 mole of HCl}=0.250\times 22.4L$
$=5.6\text{L}$
