WebOne such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? WebThe first step is to find the molar mass of H2O (water). Add up the atomic masses of: 2 hydrogens: ~1.001 * 2 = 2.002 g/mol and 1 oxygen: ~15.999 g/mol 15.999 g/mol + 2.002 g/mol = 18.001 g/mol Next, divide 45g by the molar mass: 45 g / (18.001 g/mol) = 2.5 moles Thus, there are ~2.5 moles of water in 45g of water. 1 Samed Medovic cumberland tax assessor
