Interpretation:
The mass of 5 mole of iron (III) oxide (
Concept Introduction:
Mole is SI unit which is used to measure the quantity of the substance. It is the quantity of a substance which contains same number of atoms as present in accurately 12.00 g of carbon-12 is known as mole
Number of moles is defined as the ratio of mass to the molar mass.
The ratio of mass of the given compound to the number of moles of compound is known as molar mass.
The one mole of any substance is equal to the
