How do you find molar mass
WebThis site explains how to find molar mass. Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. WebMar 30, 2024 · To find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. Adding them together yields: As such, the molar mass of NaOH is 30.997 …
