Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume. The molality describes the moles of a solute in ...

The molar volume is the volume occupied by one mole of any gas. The same value is obtained for all gases at the same temperature and pressure. The value of the molar volume will be different for ...

You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula. The ...
