2. 20.0 g of white crystals, which might have been either NaCl (MW = 58.0 g/mol) or sucrose (MW = 343 g/mol), were dissolved in 2500.0 mL of water. The density of the solution was determined to be 1.004 g/mL. At 22 °C, the osmotic pressure was measured to be 0.56 atm. Determine whether the solution is NaCl or sucrose.
