Part 1: What is the final volume in milliliters when 0.730 L of a 44.8 % (m/v) solution is diluted to 23.3 % (m/v)? part 2:A 739 mL NaCl solution is diluted to a volume of 1.50 L and a concentration of 2.00 M . What was the initial concentration?

part 1 : the final volume : 1.404 L

part 2 : the initial concentration : 4.06 M

Dilution is the process of adding a solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

M₁V₁=M₂V₂

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = Molarity volume of the solution after dilution

part 1 :

M₁=44.8%

V₁=0.73 L

M₂=23.3%

part 2 :

V₁=739 ml=0.739 L

V₂=1.5 L

M₂=2

the dependant variable is spilled water

the independent is the heat
