At 517 mm Hg and 24 °C, a sample of gas occuples a volume of 95 ml. The gas is transferred to a 225-ml flask and the temperature
vodomira [7]

Answer:

P_2=194.78mmHg

Explanation:

Hello,

In this case, we employ the combined ideal gas law in order to understand the volume-gas-pressure behavior as shown below:

\frac{P_1V_1}{T_1}= \frac{P_2V_2}{T_2}

Hence, solving for the final pressure P2, we obtain (do not forget temperature must be absolute):

P_2=\frac{P_1V_1T_2}{V_2T_1}=\frac{517mmHg*95mL*(-8.0+273.15)K}{(24+273.15)K*225mL}\\ \\P_2=194.78mmHg

Best regards.
