Question

What is the molarity of a solution containing 9.0 moles of solute in 500.0 mL of solution? Don't forget the unit.

Answer 1

Solution is 0.018 M

Step-by-step explanation:

Molarity → moles of solute in 1L of solution

A typical sort of concentration, the most common.

Solute: 9 moles

Volume of solution: 500 mL

We convert the volume from mL to L → 500 mL . 1L / 1000 mL = 0.5L

Molarity (mol/L) = 9 mol / 0.5L = 0.018 M
