Answer:

               n = 10.7142 /mol

Explanation:

               The formula for calculating mole  is given as

                              n  =   m / M   ----- (1)

Given data:

                    m = 150 g

                    M = 14g/mol

                     n = ?

Solution:

             putting values in equation (1),

                    n = 150 g / 14 g/mol

                     n = 10.7142 /mol

150 g of nitrogen = 5.35 mol of nitrogen

The formula of nitrogen is N_2.

Molar mass = 2 × 14.007 g/mol= 28.014 g/mol

Moles of N_2 = 150 g N_2 × (1 mol N_2/28.014 g N_2) = 5.35 mol N_2
