To find the molar mass of a substance, it is necessary to find the sum of the atomic masses of the elements that make up a given molecule.
According to the periodic table:
Mr (Na) = 23 g / mol
Mr (Si) = 28 g / mol
Mr (O) = 16 g / mol
Taking into account the numbers-indices standing at the atoms in the formula Na2SiO3, the molar mass is equal to:
Mr (Na2SiO3) = 23 * 2 + 28 + 16 * 3 = 122 g / mol.
