□ condition of the solution before dilute
- percent concentration : c (%)
- mass of the solution : ML (g)
- volume of the solution : V1 (ml)
- molar mass of the solute : MW (g/mol)
- specific weight of the solution : γ

□ Molarity M1 of the solution before diluted
- mass of the solute : Ma = c*ML/100
- mol of the solute : mol = Ma/MW = c*ML/(100*MW)
- volume of the solution by liter : V = ML/(1000*γ)
- M1 = mol/V = c*ML/(100*MW) / (ML/(1000*γ))
       = 10*c*γ/MW

□ volume of the pure water added for dilution : V2 (ml)

□ Molarity M2 of the solution after diluted
- M2 = V1*M1/(V1+V2) = V1*(10*c*γ/MW)/(V1+V2)
       = 10*c*γ*V1/(MW*(V1+V2))

*** 참고문헌[References] ***

M2 = 10*c*γ*V1/(MW*(V1+V2))
