    1 atomic mass unit is equal to

    The number of g-atoms of nitrogen in its 7gm is equal to number of g-atoms in:

    A mole is a collection of 6.022 xx 10^23 particles and the number 6.022 xx 10^23 is called Avogadro number. The mass of this number of atoms in an element is equal to its gram atomic mass and mass of this number of molecules in a compound is equal to its gram molecular mass. The volume occupied by this number of molecules of a gas at N.T.P is 22.4 L. When 6.022 xx 10^23 molecules of a substance are dissolved in 1L of solution, the solution is known as 1 molar volume. Suppose the chemists would have choosen 10^20 as the number of particles in a mole, the mass of 1 mole of oxygen gas would be:
