Given:

      Mole = 1

Formula:

      Moles = Given mass / Molar mass

a) Molar mass of hydrogen = 2.016

   Mass = 1 * 2.016

  Mass = 2.02g

b)Molar mass of Helium = 4

  Mass = 1 * 4

  Mass = 4g

c)Molar mass of carbon monooxide = 28

  Mass = 1 * 28

  Mass = 28g

d)Molar mass of water = 18

  Mass = 1 * 18

  Mass = 18g

The substance's intense property, the molar mass, is independent of the sample's size. The coherent unit of molar mass in the SI is kilograms per mole (kg/mol). Molar masses are, however, virtually generally given in g/mol due to historical considerations.
