What is the mass of solute in a 500 mL solution of 0.200 M sodium phosphate (Na3PO4)? (MW Na3PO4 =164.0 g/mol) g. Your answer should be rounded to the nearest tenth. Do not include units in your answer.

The mass of solute : 16.4

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

Where

M = Molarity

n = number of moles of solute

V = Volume of solution

mol Na₃PO₄

mass Na₃PO₄

you need to have a picture of the atom that way we can answer it
