What is the formula to find moles?

Moles to grams formula: grams(g) = moles(n) X molecular mass. Example: Sodium bicarbonate, NaHCO3, is one ingredient of baking powder. How many grams of sodium bicarbonate are in 0.673 moles? Step 1. Find the molecular mass: NaHCO3 = 1 Na = 1 X 22.99 g/mol = 22.99 g/mol 1 H = 1 X 1.01 g/mol = 1. read more

Moles of a chemical formula (or element) are calculated by dividing the grams of the formula by the molecular weight of the formula. The molecular weight is determined using the periodic table, where the number of atoms of each element in the formula (times the atomic weight) is summed up for the whole formula. read more
