222g of oxygen contains how many moles?
moles = grams/molar mass
13.88 mol oxygen
To determine the number of moles in 222g of oxygen, we can use the molar mass of oxygen and the formula:
Molar mass of oxygen = 16g/mol
The number of moles (n) can be calculated using the formula:
n = mass / molar mass
Substituting the given values:
n = 222g / 16g/mol
Dividing 222g by 16g/mol, we find:
n ≈ 13.875 mol
Therefore, 222g of oxygen contains approximately 13.875 moles.
