What is the molarity of the resulting solution assuming that all of the solute dissolves? - best degreaser for household use
Trisodium phosphate is sold without a prescription Na3PO4 for use in homes as a cleaner and degreaser.
You make a trisodium phosphate solution by mixing 243 g Na3PO4 in 2.00 liters of water in a beaker. What is the molarity of the solution on the basis of the assumption that all solutions will be dissolved? Please explain

M. Na 3PO4 = 3 (23) + 31 + 4 (16) = 148 g
This means that 1 mole weight Na3PO4 148g
243g is 1.642 mol.
1.642mol is dissolved in 2L of water
0.821 mol dissolved in 1 liter of water, so that a molar 0.821M.
