Find the volume, number of molecules and atoms of each element for 6 kg of hydrogen peroxide.

The molar mass of hydrogen peroxide is:

M H2O2 = 1 + 1 + 16 + 16 = 34 grams / mol;

Determine the amount of substance in 6 kilograms of hydrogen peroxide:

N H2O2 = 6000/34 = 176.47 mol;

Under normal conditions, one mole of ideal gas takes up a volume of 22.4 liters.

The volume of hydrogen peroxide will be:

V H2O2 = 176.47 x 22.4 = 3,952.93 liters;

One mole contains 6.022 x 10 ^ 23 molecules.

The number of hydrogen peroxide molecules will be:

K H2O2 = 176.47 x 6.022 x 10 ^ 23 = 1.0627 x 10 ^ 26 molecules;

One hydrogen peroxide molecule contains two hydrogen atoms and two oxygen atoms.

The number of hydrogen and oxygen atoms will be.

K H = K O = K H2O2 x 2 = 1.0627 x 10 ^ 26 x 2 = 2.1254 x 10 ^ 26 atoms;
