Question

the volume of water to be added to 100ml of 0.5M Nacl solution in order to make it deci molar

explanation:-

before dilution. After dilution


M1=0.5M. M2=0.1M
V2=?

V1=100ml


According to dilution law
M1V1=M2V2
0.5×100=0.1×V2
V2=500ml
volume of water to be added V2-V1
500-100=400ml
to make decimolar solution we can add 400ml of water
