Calculate the volume of hydrogen that will fully react according to the reaction equation with one mole of oxygen.

We write down the reaction equation.
2H2 + O2 = 2H2O.
First, using the reaction equation, we find the amount of hydrogen substance. We write down the resulting solution.
X mol H2 – 1 mol O2.
2 mol H2 – 1 mol O2.
Find the unknown value of x.
X = 2 mol × 1 mol: 1 mol = 2 mol H2.
This means that the amount of hydrogen substance is 2 mol.
Next, we find the volume of hydrogen. We use the following formula.
n = V / Vm.
V = n × Vm.
V = 2 mol × 22.4 L / mol = 44.8 L.
This means that 44.8 liters of hydrogen will react.
Answer: 44.8 liters of hydrogen will react.
