A mass of gas at 7oC and 70cm of mercury has a volume of 1200cm3. Determine its volume at 27oC and pressure of 75cm of mercury.

1200cm3

1378cm3

4320cm3

4629cm3

Answer Details

\frac{V_{1} P_{1}}{T_{1}}

=

\frac{V_{2} P_{2}}{T_{2}}

$\frac{70 \times 1200}{7 \times 273}$ = $\frac{75 \times V_{2}}{27 + 273}$

V2 = 1200cm3
