325 mL of solution was prepared by dissolving an 8.475 g sample containing sodium nitrate (NaNO3) and sodium phosphate (Na3PO4) in water. The analysis of the sodium content led to the formation of 0.2924 g NaCl after extraction of the analyte for a 50 mL sample. Phosphates from a second 50 mL sample was precipitated as MgNH4PO4. After calcination, 0.1226 g Mg2P2O7 was found. Calculate the NaNO3 and Na3PO4 mass fractions ● 6 H2O of the sample
