A student needs to dilute a 0.46 M Pb ( NO3 ) 2 solution to make 55.0 mL of 0.14 M Pb ( NO 3 ) 2 . Set up the calculation by placing the values with the correct units into the equation. Then, calculate the volume, in milliliters, of the 0.46 M Pb ( NO 3 ) 2 solution that is needed.

16.7mL

Explanation:

From the information provided, the following were obtained:

C1 = 0.46 M

V1 =?

C2 = 0.14M

V2 = 55mL

Using the dilution formula, (C1V1 = C2V2).., we can obtain the volume (V1) of original solution as follows:

C1V1 = C2V2

0.46 x V1 = 0.14 x 55

Divide both side by 0.46

V1 = (0.14 x 55) / 0.46

V1 = 16.7mL

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
