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
