A student started with a mixture containing 3.21 mL toluene and 3 mL ethyl acetate for their simple distillation and their refractive index data is below.Fraction #Refractive Index11.416521.427631.441041.449951.473761.4776Then, for their fractional distillation, they started with a mixture containing 2.97 mL toluene and 3.06 mL ethyl acetate. The refractive index data for their fractional distillation are below. Fraction #Refractive Index11.379821.394031.417641.469951.477561.4919In the experiment, the student measured the refractive indices of toluene and ethyl acetate to be 1.4941 and 1.3720, respectively. How many theoretical plates did they achieve in their fractional distillation? Enter your answer to 2 decimal places (i.e. N.NN). Some other data that may be useful:density of toluene: 0.8623 g/mLdensity of ethyl acetate: 0.9020 g/mL
