How do you find molar mass
WebAgain the molar mass of a chemical says how many grams are contained within 1 mole of that chemical. So we can take our mole number from before and multiply it by the molar mass: 0.00625 mol x (45.4622 g/1 mol) = 0.27788875 g. Accounting for sig figs the answer is properly reported as 0.28 grams of beryllium chloride.
