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.

answer; /// i do believe that the correct answer is (c)nuclear bond

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
