Question

A gas occupied one litre under atmospheric pressure. What will be the volume of the same amount under $750$mm of $Hg$ at the same temperature?

• A. $1.0133$ litre
• B. $2.0133$ litre
• C. $3.0133$ litre
• D. $5.0133$ litre

Answer 1

The correct option is A $1.0133$ litre

$P_1=1atm$
$V_1=1L$
$P_2=\frac{750}{760}atm$(at same T)

$⟹P_1{V}_1=P_2{V}_2$

$⟹1\times 1=\frac{750}{760}\times V_2$

$V_2=1.0133L$
