Question

 

Using this percent change data, determine the concentration of sucrose that would be isotonic. 

it  does not have to be exact 

Write your answer with 1 digit past the decimal point - e.g. 8.6 (a trailing zero is considered a digit)

 

 

Isotonic concentration =    Moles

 

  • 0.0 M sucrose -0.24×100÷4.6= -5.2%
  • 0.4 M sucrose = 0.39×100/4.2=9.3%
  • 0.6 M sucrose = 0.7×100÷4=17.5% 
  • 0.8 M sucrose =0.8×100/3.7=21.6%
  • 1.0 M sucrose =0.4×100/4.6=8.7%
