0.644 moles First, calculate the number of moles of sodium phosphate by multiplying volume times molarity. 0.716 l * 0.450 mol/l = 0.3222 mol When dissolved in water, sodium phosphate breaks up into 2 ions, so the number of ions is 2 * 0.3222 mol = 0.6444 mol So there will 0.644 moles of ions present.
