The formula for sodium dihydorgen phosphate heptahydrate is: NaH2PO4.7H2O To determine the mass % of sodium you first need to find the total mass: 1 Na = 1 x 22.990 = 22.990 16 H = 16 x 1.0079 = 16.1264 1 P = 1 x 30.97 = 30.97 11 0 = 11 x 15.9994 = 175.9934 Total = 246.084 g For the mass % of Sodium: (22.99 g Na/246.084 g total)x 100% = 9.34%
