Q4 of 27 Page 46

Find the number of gram atomic masses in each of the following.

70 g of nitrogen


(Atomic mass He = 4, O = 16, N = 14, Ca = 40)

Given: Mass of nitrogen = 70g

Atomic mass of nitrogen = 14


1 GAM of nitrogen = 14g


Apply the formula given below:





Number of gram atomic mass = 5


Thus, number of gram atomic mass of nitrogen is 5
