Ihave 345 ml of a 1.5 m nacl solution. if i boil the water until the volume of the solution is 250 ml, what will the molarity of the solution be: ?

The final molarity of the solution will be 2.07 M

From the question given above, the following data were obtained:

The final molarity of the solution can be obtained as follow:

M₁V₁ = M₂V₂

1.5 × 345 = M₂ × 250

517.5 = M₂ × 250

Divide both side by 250

M₂ = 517.5 / 250

M₂ = 2.07 M

Thus, the final molarity of the solution is 2.07 M

The molarity of the new solution prepared will be 2.07 M

M₁V₁ = M₂V₂

Where;

According to this question, the following data were given:

M₁V₁ = M₂V₂

1.5 × 345 = M₂ × 250

517.5 = M₂ × 250

M₂ = 517.5 / 250

M₂ = 2.07 M

Therefore, the molarity of the new solution is 2.07 M.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
