Dear student,

The concentration of NO3 will be 0.2 M

[NO3]- in 0.1M AgNO3=0.1M

When mixed with equal volume of 0.2M NaCl Solution,

The volume of the solution is double.So Concentration of NO3- is halved.

[NO3-]=0.1/2=0.05M

Dear ajesh,

In this the NO3- ions are coming from the compound AgNO3.And its normality aswell as molarity will be 0.1 in magnitude.

When it free its(NO3-) concentration = 0.1 M

But the equal amount of another is added , we know that concentration is inversely proportional to volume. When volume is doubled means concentration will be halved.So required concentration = 0.1/2=0.05

All the best.
