If `N_(A)` is Avogadro's number, then the number of oxygen atom in one g-equivalent of oxygen is

Number of oxygen atoms in product x

Avogadro's number N_(A) is

Atoms and molecules are so small in size that it is neither possible to count them individually nor possible to determine their mass. These are counted collectively in terms of Avogadro's number. The mass of Avogadro's number of atoms and molecules is known as gram atomic mass and gram molecular mass respectively. The volume occupied by Avogadro's number of molecules of a gas or vapours is known as molar volume. If N_(A) is Avogadro's number, then the number of valence electrons in 4.2 g of nitride ions (N^(3-)) is :

Number of oxygen atoms in molybdate ion is

If N is Avogadro's number, then the number of molecules in 6 g of hydrogen at NTP is

Number of oxygen atoms in pyrosillicate is
