Q4 of 27 Page 46

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

200 g of oxygen


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

Given: Mass of oxygen = 200g

Atomic mass of oxygen = 16


1 GAM of oxygen = 16g


Apply the formula given below:





Number of gram atomic mass = 12.5


Thus, number of gram atomic mass of oxygen is 12.5.
