The gram Atomic Mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
To calculate the number of grams of sodium in sodium phosphate, we need to know the molar mass of sodium phosphate (Na3PO4). The molar mass of Na3PO4 is 164.0 g/mol. Since there are 3 sodium atoms in one molecule of Na3PO4, the molar mass of sodium in Na3PO4 is 22.99 g/mol. Therefore, there are 7.2 g * (22.99 g/mol / 164.0 g/mol) = 1.01 grams of sodium in 7.2 grams of sodium phosphate.

How many grams of sodium hydroxide are present in 675 mL of a 0.500M solution?
To calculate the grams of sodium hydroxide present in the solution, first calculate the number of moles using the formula: moles = Molarity (M) x Volume (L). Then, use the molar mass of sodium hydroxide (NaOH) to convert moles to grams. The molar mass of NaOH is 40 g/mol. Thus, in this case, you have 0.3375 moles of NaOH and if you convert this to grams, it would be 13.5 grams.
