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.

A.

1200cm3

B.

1378cm3

C.

4320cm3

D.

4629cm3

View answer & explanation

Correct answer is A

\(\frac{V_1P_1}{T_1}\) = \(\frac{V_2P_2}{T_2}\)

\(\frac{70 \times 1200}{7 \times 273}\) = \(\frac{75 \times V_2}{27 + 273}\)

V2 = 1200cm3
