$V_{2} = 254.6 m L$ $V_2=254.6 mL$

Explanation:

For this question we would use Boyle's equation for the relationship between Pressure and Volume

$P_{1} V_{1} = P_{2} V_{2}$ $P_1V_1=P_2V_2$

$P_{1} = 645 m m H g$ $P_1 = 645mmHg$
$V_{1} = 300 m L$ $V_1=300mL$
$P_{2} = 1 a t m = 760 m m H g$ $P_2=1atm = 760mmHg$
$V_{2} = ?$ $V_2=?$

$645 m m H g (300 m L) = 760 m m H g (V_{2})$ $645mmHg(300mL)=760mmHg(V_2)$

$\frac{645 m m H g (300 m L)}{760 m m H g} = \frac{760 m m H g (V_{2})}{760 m m H g}$ $(645cancel(mmHg)(300mL))/(760cancel(mmHg))=(cancel(760mmHg)(V_2))/(cancel(760mmHg))$

$254.6 m L = V_{2}$ $254.6 mL = V_2$
