     A student records the following information: 

     Mass of empty 150-mL beaker: (6.4750 × 10^1) g 

     Mass of 150-mL beaker + water: (1.864 × 10^2) g 

     Initial mass of sodium chloride in 2nd beaker: (1.6 × 10^2) g 

     Final mass of sodium chloride in 2nd beaker: (9.7940 × 10^1) g 

     Calculate the mass percent of the sodium chloride solution in % by mass. 

     Report your answer to three significant figures.

     Mass of water = (1.864 × 10^2) g  - (6.4750 × 10^1) g = 121.65 g

    beaker = 64.75 g

    beaker+water = 186.4 g

    initial mass of NaCl + 2nd beaker = 106 g

    final mass of NaCl + 2nd beaker = 97.94 g

    ?? you have, apparently, 2 beakers. You have mass of first, but not mass of second.

    Also unknown is what causes the mass of NaCl to change 

    too much missing data.
