Question

A 350. mL air sample collected at 35°C has a pressure of 550. torr.
What pressure will the air exert if it is allowed to expand to 425 mL at 57°C?

Answer 1

$\tt \dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

T₁ = 35 + 273 =308 K

T₂ = 57 + 273 =330 K

550.350/308 = P₂.425/330

P₂ = 485.29 torr
