Question

calculate the amount of surfactant (mol mass =200) absorbed on 3% activated charcoal in mg/gm if an actual surfacent amount of 0.030 molar has surface tension value of 45mN/m​

Answer 1

Answer:

Calculate the amounts of surfactant (molecular mass = 200 g/mol) adsorbed onto 3.0% activated charcoal in milligram per gram unit (mg/g) if an actual surfactant amount of 0.030 molar has surface tension value of 45 mN/m? (Note: the concentration of pure surfactant solution at 45 mN/m is 0.00001 molar) a. None b. 66.6 c. 133.0 Od 200.0 N
