Question

What is the concentration of nitrate ions in 2.00L of a solution that contains 0.250 moles of Fe(NO3)3 ?

The answer is ....0.375M, but how?

A 150. mL salt solution is prepared by diluting a 25.0 mL sample of a more concentrated solution. The

concentration of the diluted salt solution is 0.550 M. What was the concentration of the undiluted salt solution?

How is the answer.... b) 3.30 M and not .0917??
