Question

Calculate the volume of water which could be added to 20ml of 0.65m hcl to dilute the solution to 0.2m

Answer 1

Answer:

The volume of water to be added is 45ml

Explanation:

Acc. to dilution formula,

M1xV1=M2xV2

M1=O.65M

M2=0.2M

V1=20ml

Let amount of water added be x

so total volume of solution(V2) is x+20 ml

0.65 x 20=0.2 x (x+20)

65=x+20

x=45ml

Hope you got the answer
