Question

The active mass of 7g of nitrogen in a 2l container would be

Answer 1

active mass means molarity.
molarity=n/V
here n=7/14 =0.5
therefore active mass=0.5/2
=0.25

Answer 2

¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
=>Molecular weight of N2=28

=>Mole of N2 = 7/28=1/4 mole =0.25

=>Active mass = 0.25/2=0.125 mol L -¹

¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
Active mass is nothing but concentration or molarity
