select all that apply which of the following are used to express concentration? percentages calories weight per volume molarity
Answer
Brief Explanations:
Percentages (e.g., mass - percentage, volume - percentage) can express the proportion of a solute in a solution. Weight per volume (e.g., g/mL) gives the amount of solute per unit volume of solution. Molarity (moles of solute per liter of solution) is a common way to express concentration in chemistry. Calories measure energy and are not related to concentration.
Answer:
A. Percentages C. Weight per volume D. Molarity
