Question

What is the molarity of an aqueous solution made by diluting 38 grams of sodium carbonate to a volume of 4,400mL?

Answer 1

You have to divide 38 grams by the molar mass of sodium carbonate to get moles

38/106= .35 moles

Then divide 4,400ml by 1,000 to get liters

4,400/1,000= 4.4 l

Then divide moles by liters to get molarity


.35/4.4= .079M
