Gas Law Chemistry

Question

At standard temperature, a gas has a volume of 337 mL. The temperature is then increased to 127◦C, and the pressure is held constant. What is the new volume?

Answer 1

Since the moles of gas is constant PV/T has the same value for both conditions.

[ P₁V₁] /T₁ = [P₂V₂]/T₂

you know T for both conditions. Pressure is constant, so the P's cancel. V₂ is the only unknown.
