Question
What is the molarity of a solution prepared by dissolving 820. g of sodium phosphate, Na3PO4, in water and diluting to 2.89 liters?
(atomic masses: Na = 22.99, P = 30.97, O = 16.00)
(atomic masses: Na = 22.99, P = 30.97, O = 16.00)

How many mols do you have? That's mols = grams/molar mass = ?
Then M = mols/L solution (which is 2.89L)
Then M = mols/L solution (which is 2.89L)
