Question

a total of 1.4 moles of sodium nitrate is dissolved in enough water to make 2.0 liters of an aqueous solution. the gram-formula mass of sodim notrate is 85 grams per mole. determine the molarity of the solution

Answer 1

1.4 moles/ 2.0 L= 0.7 M

Explanation: Molarity= moles of solute/ Liters of solution

therefore just plug the numbers in and you'll find the molarity to equal. 0.7
