Suppose that at STP a gas occupies 10.2 L. At what temperature (°C) will the same gas occupy 15000 mL at 1550 torr?

Using the combined gas law:

(P₁V₁/T₁) = (P₂V₂/T₂)

Plug in the given values:

(1 atm)(10.2 L)/(273 K) = (1550 torr)(0.015 L)/T₂

Solve for T₂:

T₂ = (1550 torr)(0.015 L)/(1 atm)(10.2 L)(273 K)

T₂ = 545 K = 272 °C

Convert to Celsius:

T₂ = 272 − 273 = −1 °C

Therefore, the gas will occupy 15000 mL at 1550 torr at −1°C.
