Application of Charles's Law (one of the derived basic gas laws) to calculate volume at a different temperature.

A certain mass of calcium carbide, CaC2, reacts completely with water to produce 64.5 L of acetylene, C2H2, at 50 degrees C and 1 atm. If the same reactants react completely at 300 degrees C and 1 atm, what will be the volume of acetylene?

First, we have to realize that the pressure is unchanged, thus the volume and the temperature are the only variables. The gas law, which is derived for constant ...
