# Calculate the mass of sodium oxide in the amount of 2 mol.

January 13, 2021 | education

| Sodium oxide formula: Na2O. Let’s determine its molar mass according to the periodic table: M = 23 * 2 + 16 = 62 g / mol. Using the formula m = n * M (where n is the amount of sodium oxide substance, equal to 2 mol), we calculate the mass of the oxide. m (Na2O) = 2 mol * 62 g / mol = 124 g.

Answer: the mass of oxide is 124 g.
