Web10 okt. 2024 · First start off by figuring out the formula mass of MgSO4 * 7H2O, which is 246.48 g/mol Then, divide the amount of grams of the sample by the molar mass After finding out the amount of moles of the sample, you can multiply the mole ratio to find the number of moles of oxygen Web3 jan. 2024 · Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. WebThe molar mass of MgSO4 is 120.38 g/mol.
