Answer 2

Answer:

n-factor for Na2CO3 =2

∵ The n-factor of such salts is defined as the number of moles of electrons exchanged (lost or gained) by one mole of the salt. And there is the exchange of 2 electrons so its n factor is 2

Therefore, Normality = n-fator × molarity

Molarity = 2/ 0.2

=0.1 M

Hence, the correct option is C
