at 25^{0} C and 730 mm pressure, 730 ml of dry oxygen was collected. if the temperature is kept constant what volume will oxygen gas occupy at 760 mm pressure?

The numerical will be solved by Boyle's Law which says :

At constant temperature,for a fixed mass of gas,volume is inversely proportional to pressure.

PV=constant

Formula used :

P

_{1}V

_{1}=P

_{2}V

_{2}

Here,P

_{1}=730mm

P

_{2}=760mm

V

_{1}=730ml

V

_{2}=?

${\mathrm{V}}_{2}=\frac{{\mathrm{P}}_{1}{\mathrm{V}}_{1}}{{\mathrm{P}}_{2}}\phantom{\rule{0ex}{0ex}}=\frac{730\times 730}{760}\phantom{\rule{0ex}{0ex}}=\frac{532900}{760}\phantom{\rule{0ex}{0ex}}=701.18\mathrm{ml}$
