Question

What does it mean when say that a 200-ml sample and a 400-ml sample of a solution of salt have the same

Answer 1

Answer:

Read explanation.

Explanation:

Molarity is a unit used to measure the $\frac{solute}{solution}$ ratio per unit volume of the solution. So, in other words, and in our case, we call it the $\frac{moles~of~salt}{per~ml~of~solution}$ ratio.

So, the amount of solute (moles of salt) per ml of solution will be the same, but the number of moles in each solution will be obviously different.
