Question

The volume of a gas at ${27}^{o}C$ and $760mm$ Hg is $500cc$. Then its volume at same temperature and $380mm$ Hg is:

• A. $500cc$
• B. $1000cc$
• C. $750cc$
• D. $1500cc$

Answer 1

The correct option is B $1000cc$

$PV=nRt$
$PV=constant$
$\left(760\right)\left(500cc\right)x\left(380\right)\left(v\right)$
$v=\frac{760\times 500}{380}$
$=1000cc$
