CHM 142 Lecture 2: Like dissolves like

Molarity (M) is the number of moles of a solute per 1 L of solution--> M= (mol solute)/(L solution). How many moles of permanganate are in 5.53 L of a 7.85 M solution?

What is the molarity of the following solutions?

a. 1.25 L of solution contains 0.455 mol of solute.

b. 250 mL of solution contains 0.215 mol of solute.

c. 0.175 mol of solute is put into a container and enough distilled water is added to give 100 mL of solution.
