Question

The initial volume of a gas cylinder is 750.0 ,mL. If the pressure of gas inside the cylinder changes from $840.0 \,mm$ Hg to 360.0 mm Hg, the final volume the gas will be :

• A. 1.750 L
• B. 3.60 L
• C. 4.032 L
• D. 7.50 L

Answer 1

Answer: (A)

1.750 L

Answer 2

$P_{1} V_{1}=p_{2}v_{2}$
$\Rightarrow 840\times752=360\times v_{2}$
$\Rightarrow v_{2}=\frac{840\times750}{360}$
$= 1750 \,ml$
$= 1.75\, L$
