A gram(g) is a metric unit of mass and was formally defined as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter, and at the temperature of melting ice.

While a mole is the unit of measurement for amount of substance in the International System of Units.

**Formula to convert moles to grams.**

To convert moles to g, we multiply the moles by the molar mass also known as the molecular weight.

**Grams = Moles x Molar Mass**

**Example: **

Convert 0.2 moles of Sodium chloride.

Since we know the molar mass of NaCl is 58.44g/mol, therefore we will multiply it by 0.2 to get grams.

**= 0.2 x 58.44**

**= 11.688 grams.**
