Please Solve D and E Calculate the molar was and identify the sample
2 . A student performs an experiment designed to determine the molar mass of a sample of anunknown volatile liquid . The following data was collected :"DataMass of Erlenmeyer , foil , and rubber band77.523 9Temperature of boiling water bath99.5′ CMass of Erlenmeyer , rubber band , foil and condensed vapor( after cooling )77.923 9Barometric pressure0. 997 atmMass of Erlenmeyer and water ( 22.0 0 0 )232 . 12 92 . Determine the mass of the condensed unknown .b. Assuming the density of water to be 0. 99 9 / ml at 22. 0 0 0 ) , determine the total volume of theErlenmeyer ."C . Starting with the ideal gas law , substitute the fact that n is equal to grams / molar mass andderive an expression for calculating the experimental molar mass of the student’s volatile liquidsample ."J . Calculate the molar mass for this student’s sample .8 . Identify the unknown sample from data provided in Appendix !
