Question

The volume of a given mass of a gas is 300 ml, measured at 798 mm pressure. What will be the volume, if pressure is reduced to 760 mm at constant temperature?

• A. 315 ml
• B. 513 ml
• C. 135 ml
• D. 360 ml

Answer 1

The correct option is A 315 ml

According to Boyle’s Law
$P_1{V}_1=P_2{V}_2$ or 798 $\times$ 300=760 $\times V_2$
$\Rightarrow V_2=\frac{798\times 300}{760}=315ml$
