WebApr 7, 2024 · Add together the atomic masses from your solute to find the total molar mass. Label the final measurement in g/mol. [9] For example, if your solute is potassium hydroxide (KOH), find the atomic masses for potassium, oxygen, and hydrogen and add them together. In this case molar mass = 39 +16 + 1 = 56 g/mol.
WebThe former has a molar mass of 12 g/mol, and the latter a molar mass of 16 g/mol. Since there are 2 moles of oxygen atoms in every mol of carbon dioxide, the total molar mass due to oxygen is 2 x 16 g/mol = 32 g/mol. The resulting molar mass of carbon dioxide is therefore 12 g/mol + 32 g/mol = 44 g/mol. d3s to ledWebThis chemistry video tutorial explains how to calculate the molar mass of a compound.
