Chemistry

A 2.500×10−2M solution of NaCl in water is at 20.0∘C. Thesample was created by dissolving a sample of NaCl in water and thenbringing the volume up to 1.000 L. It was determined that thevolume of water needed to do this was 999.3 mL . The density ofwater at 20.0∘C is 0.9982 g/mL.

Calculate the molality of the salt solution. XNaCl =2.506 X 10-2 m

Calculate the mole fraction of salt in this solution.XNaCl = ???

Calculate the concentration of the salt solution in percent bymass. Percent by mass NaCl = ???

Calculate the concentration of the salt solution in parts permillion. Parts per million NaCl = ???
