Molarity practice

Question

80.0 grams of NaOH is dissolved in water to make a 6.00L solution. What is the molarity of the solution?

Answer 1

Molarity is moles per liter.

We are given that there is 6 L of solution and 80 grams of NaOH.

You can convert grams to moles by dividing number of grams by molar mass of NaOH (39.997).

80/39.997= 2.00 moles

2 moles/6 L= 0.33 M
