If you dilute 16.0 ml of the stock solution to a final volume of 0.310 l, what will be the concentration of the diluted solution

Assume that the concentration of stock is 1.0 M

And initial volume = 16.0 ml

final volume = 0.310 L or 310 ml

therefore

CiVi = CfVf

1.0 * 16 ml = Cf * 310 ml

Cf = 1.0*16/310

= 0.052 M

Thus dilute solution is 0.052 M times dilute to concentrate solution
