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.
Web9 jun. 2024 · It is known that number of moles is equal to mass divided by molar mass of the compound or substance. Since, it is given that mass is 10 g and molar mass of ethanol is 46.07 g/mol.
