Monobasic refers to the presence of one electron donor (base), in this case the sodium (Na) so the chemical formula for monobasic sodium phosphate is NaH2PO4. Monohydrate refers to how hydrated, or...
A mole of sodium phosphate, Na3PO4, weighs about 163.94 grams. This contains about 68.97 grams of Na. This shows sodium phosphate to be about 42.07% sodium by mass.
Sodium phosphate is Na3PO4, which means each molecule of sodium phosphate is four atoms of oxygen bound to a central phosphorus atom, with three sodium atoms arranging themselves randomly to three of...
