BRAINCAKEMolar Volume Calculation - 2
Many reactions produce a gas, and the molar volume lets you predict the volume of gas from the mass of a reactant. The method always has three steps:
1. Find the amount of the known substance: amount = mass ÷ Mr
2. Use the mole ratio from the balanced equation to find the amount of gas.
