Question

What would be the experimental molecular weight of benzoic acid if dissolved in kerosene?

Answer 1

Question: 1- what is the "experimental" molecular weight of Benzoic Acid in g/mol the mass of benzoic acid ...

1- what is the "experimental" molecular weight of Benzoic Acid in g/mol the mass of benzoic acid is 1.068 g

the mass solvent is lauric acid= 8.084g

molality= 1.01

Tf= 38.3

kf=3.9

moles of benzoic acid = 0.01 mol

2- determine the accepted molecular weight for benzoic acid from its formula.

3- calculate the percent error.

4- what is the major sources of error in the experiment.

5- suppose your thermometers consistently read a temperature 1.2 lower than the correct temperature. how would this have affected the molar mass you
