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.
