Calculate the volume and number of molecules that 96 g of oxygen takes.
September 20, 2021 | education
| The molar mass of oxygen is:
M O2 = 16 x 2 = 32 grams / mol;
Let’s determine the amount of substance in 96 grams of oxygen:
N O2 = 96/32 = 3 mol;
Under normal conditions, one mole of ideal gas takes up a volume of 22.4 liters.
The oxygen volume will be:
V O2 = 3 x 22.4 = 67.2 liters;
One mole contains 6.022 x 10 ^ 23 molecules.
The number of oxygen molecules will be:
K O2 = 3 x 6.022 x 10 ^ 23 = 1.8066 x 10 ^ 24 molecules;
