It depends on the substance.
A mole is not a unit of mass. It is a unit of quantity, kind of like how "a dozen" means twelve. Except, instead of twelve, it means 6.02*10^23 of something, or
610,000,000,000,000,000,000,000. This number is known as "Avagadro's number"
Usually, a mole refers to a number of atoms or molecules. Avagadro's number is special because an avagadro's number of Atomic Mass Units (the mass of a proton) is equal to one gram.
So, one mole of Hydrogen, which has an atomic mass of 1.008, has a mass of 1.008 grams.
