Expert Answer:

Given:
N1= 0.25N
V1= 40 ml
N2 = decimolar  = 0.1
V2 =?
 
straight N 1 straight V 1 space equals space straight N 2 straight V 2

straight V 2 space equals space fraction numerator straight M 1 straight V 1 over denominator straight M 2 end fraction

space space space space space space space space equals space fraction numerator 0.25 cross times 40 over denominator 0.1 end fraction
space space space space space
space space space space space space space space equals space 100 ml

Volume space of space water space added space equals space 100 minus 40 equals space 60 ml
