2)

They are ratios of the dilution over the concentration.

3)

They are inversely related.

4)

Both measure dilution.

Answer 1

A. Both are ratios of the amount of solute over the amount of solution.

Hope this helps! :D

Step-by-step explanation:

Answer 2

The correct answer is - Both are ratios of the amount of solute over the amount of solution.

Step-by-step explanation:

Molarity is the number of moles of a substance in 1 liter of the solution. Another unit of the concentration, weight percentage, refers to the ratio of the mass of the solute (a dissolved substance) to the mass of the solution.

Molarity is to divide moles by liters, but the convention in mass percent is to divide grams by milliliters. If you prefer to think only in terms of liters (not milliliters), then simply consider mass percent as kilograms divided by liters.
