1.)  What is the concentration after the dilution of the following?

a.     14.64 mL of 0.446 M K2SO3 is diluted to 56.95 mL. New Molarity?

b.     14.64 mL of 0.446 M K2SO3 is diluted to 56.95 mL, and 12.84 mL of this solution is diluted to 49.95 mL. New Molarity?

What is the concentration after the dilution of the following? 14.64 mL of 0.446 M K2SO3 is diluted to 56.95 mL. New Molarity? 14.64 mL of 0.446 M K2SO3 is diluted to 56.95 mL, and 12.84 mL of this solution is diluted to 49.95 mL. New Molarity?

Explanation / Answer

A)M1V1=M2V2

14.64*0.446=56.95*M2

M2=0.114M

B)M2V2=M3V3

0.114*12.84=M3*49.95

M3=0.0294M
