Answer to Question #244962 in General Chemistry for leo

Question

You have a sample of gas in a flask with a volume of 250 mL. At 25.5 °C, the pressure

of the gas is 360 mm Hg. If you decrease the temperature to −5.0 °C, what is the gas

pressure at the lower temperature?

Answer 1

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

$\frac{360}{(273+25.5)}=\frac{P_2}{(273-5)}$

$P_2=\frac{360×268}{298.5}=323.22mmHg$
