Given a 1.50 Liters of solution that contains 62.5 grams of magnesium oxide. What is the Molarity of that solution? Please show all work for any credit.

Answer :

JavierCollante
Molarity= moles/ liters

first you need to calculate the moles using the molar mass of the molecule to convert grams to moles

molar mass MgO= 40.3 grams/ mole

62.5 gram MgO (1 mole/ 40.3 grams)= 1.55 mole

Molarity= 1.55 mole/ 1.50 Liters= 1.03 M
