A scientist wants to make a solution of tribasic sodium phosphate, Na_3PO_4, for a laboratory experiment. How many grams of Na_3PO_4 will be needed to produce 550 mL of a solution that has a concentration of Na^+ ions of 0.500 it M?

  • chemistry -

    You want 0.5 M in Na^+. That will be 0.5/3 in Na3PO4.
    M = moles/L soln
    Substitute M and L and solve for moles.
    moles Na3PO4 = grams/molar mass.
    Solve for grams.
