If a 500.0 mL of a 15.0M solution acetic acid are added to 500.0 mL of
water, what is the new concentration? *

Sagot :

Ardni313idn

The new concentration : 7.5 M

Further explanation

Given

500.0 mL(0.5 L) of a 15.0M solution acetic acid

500.0 mL(0.5 L) of  water

Required

The new concentration

Solution

Dilution is the process of adding 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

Input the value :

M₂=(M₁V₁)/V₂

M₂=(15x0.5)/1

M₂=7.5 M
