According to our saturated NaCl lab, it was determined that the saturation point of NaCl (MM = 58g/mol) at 20^oC was 34 g NaCl/100 g H₂O. The volume of this solution was determined to be 112 mL. Based on this information, answer the following problems. This information is also shown in the table below.

null
