Question

The number of atoms in 7g of nitrogen is (N=Avagadro number)​

Answer 1

Answer:

0.5 moles or 3.011*10^23

Explanation:

atomic mass of nitrogen=14u

mass of 1 mole of ntirogen=14g

given mass = 7g =14/2 g

so number of atoms = avagadro number/2

                                  =6.022*10^23/2

                                  =3.011*10^23 atoms
