Problem: A flask contains 0.500 mol of liquid bromine, Br2. Determine the number of bromine molecules present in the flask.Express your answer numerically in molecules.You can extend the analysis to samples of a given mass using the molar mass of a compound, which is the mass of a mole of the compound. The molar mass of N2 is 28.01 g/mol. Therefore you can say that a mole of N2 has a mass of 28.01 g and contains 6.022×1023 molecules of the gas.
