Question

#1: The concentration of a solution can be described in several ways. In which of these ways do you calculate the moles of a solute divided by the kilograms of solvent? A. molality B. molarity C. mole fraction D. mass percent

Answer 1

Molality

Step-by-step explanation:

The other answer has a very helpful explanation! I just confirm for others that this is correct on my test!

Answer 2

The answer is A. molality

A molality is a property of a solution that can be described as the number of moles of a solute divided by the kilograms of solvent

A molarity is a property of a solution that can be described as the number of moles of a solute divided by the litres of the solution.
Mass percent is a property of a solution that can be described as the grams of a solute divided by the grams of the solution and multiplied by 100 (because it is percentage)
Mole fraction is a property of a solution that can be described as the moles of the component divided by total moles of the solution.
