Question 1. A 2.700×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.3 mL . The density of water at 20.0∘C is 0.9982 g/mL. a.)Calculate the molality of the salt solution. B.) Calculate the mole fraction of salt in this solution. C.) Calculate the concentration of...

What is the molarity of an aqueous solution that is 4.97 % NaCl by mass? (Assume a density of 1.02 g/mL for the solution.) (Hint: 4.97 % NaCl by mass means 4.97 g NaCl/100.0 g solution.)
What is the molarity of an aqueous solution that is 6.16 % NaCl by mass? (Assume a density of 1.02 g/mL for the solution.) (Hint: 6.16 % NaCl by mass means 6.16 g NaCl/100.0 g solution.)
