Question

A chemist dilutes 77.9 ml of 5.50 M sodium chloride to make a 1.93 M solution. What is the final volume of the diluted solution (in ml)

Answer 1

221.9 mL is the final volume

Step-by-step explanation:

Let's apply the dilution formula to determine the volume.

Concentrated M . Concentrated volume = Diluted M . diluted volume

5.50 M . 77.9 mL = 1.93 M . diluted volume

(5.50 M . 77.9 mL) / 1.93M = diluted volume → 221.9 mL
