Calculate the volume of carbon dioxide and the mass of water that are formed during

Calculate the volume of carbon dioxide and the mass of water that are formed during the combustion of methane, taken in an amount of 1.25 mol.

The combustion reaction of methane is described by the following chemical reaction equation:

CH4 + 2O2 = CO2 + 2H2O;

It takes two moles of oxygen to burn one mole of methane. This produces two moles of water.

The required amount of oxygen is 1.25 x 2 = 2.5 mol.

Find the volume of 2.5 mol of oxygen.

The molar volume of an ideal gas is constant and occupies a fixed volume of 22.4 liters, regardless of the composition.

V O2 = 2.5 x 22.4 = 56 liters;

Let’s find the mass of 2.5 mol of water.

M H2O = 2 + 16 = 18 grams / mol;

m H2O = 2.5 x 18 = 45 grams;
