just the numerical value.
Expert Solution
Step 1: Required formula
Dilution : Addition of solvent to the solution is called dilution
In dilution process number of moles of solute remains same
Molarity (M) = n / V
MV = n
Where n = number of moles of solute , it is constant in dilution
Hence
MV = constant
Therefore
Dilution principle is
M1 V1 = M2 V2
