Find the volume of hydrogen that will react with 8g of oxygen.

The reaction of oxygen and hydrogen takes place according to the following formula:

2H2 + O2 = 2H2O

Two hydrogen molecules react with one oxygen molecule. This produces two water molecules.

Let’s find the number of moles of a substance in 8 grams of oxygen.

The molar mass of oxygen is 16 x 2 = 32 grams / mol.

8 grams of oxygen is 8/32 = 0.25 mol

In accordance with the chemical reaction equation, 0.5 mol of hydrogen will react with 0.25 mol of oxygen.

Under normal conditions, 1 mole of any gas takes up a volume of 22.4 liters.

0.5 mol of hydrogen will take up a volume of 22.4 x 0.5 = 11.2 liters.

Answer: 11.2 liters of hydrogen will react with 8 grams of oxygen.
