Question

200ml,0.2M hcl is diluted to get 0.05 M hcl.find final volume of solution

Answer 1

Answer:

M1*V1=M2*V2

here,

M1=0.2

M2=0.05

V1=200ml

V2=?

using M1*V1=M2*V2 we get

0.2*200=0.05*V2

V2=0.2*200/0.05

V2=40/0.05

V2=800

therefore volume of new solution=800ml or 0.8 litre

hope it helps
