Homework Help: Chemistry (URGENT)

Posted by John on Wednesday, December 15, 2010 at 8:18pm.

Calculate the molarity of the Co^2+ ion in each of the solutions 1-5. The new molarity is given by the molarity of the stock solution multiplied by the dilution factor.

Solution: Co(NO3)2

Original molarity: 0.160

Dilution #1: none
D#2: 12mL to 16mL
D#3: 8mL to 16mL
D#4: 4mL to 16mL
D#5: 2mL to 16mL

Please help I do not understand what I'm supposed to do. Thank you.
