Density of sea Water =1.10 g/ml
Weight of 100 ml Sea water = 110 g
Weight of NaCl in 100 ml sea water=2.8 g
%(w/w) concentration of NaCl = 2.8/110*100 = 2.55%
Answer is b) 2.55%

If the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of H2O at a given temperature, how many grams of NaCl can be dissolved in 250.0 mL of H2O? If the solubility of glucose (C6H12O6) is 120.3 g/100 mL of H2O at a given temperature, how many grams of C6H12O6 can be dissolved in 75.0 mL of H2O? Only 0.203 mL of C6H6 will dissolve in 100.000 mL of H2O. Assuming that the volumes are additive, find the volume/volume...
