How do you convert grams to moles of an element?

How do you convert from grams to moles?

Using a calculator, divide the number of grams by the molar mass. The result is the number of moles in your element or compound. For example, imagine you have 2 g of (NH4)2S and you want to convert it to moles. The molecular mass of (NH4)2S is 68.17g/mol.

What is the formula for calculating moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
