No. They didn't give you that in the problem. How can 6.243 g be 6.243 moles. A mole is a mole. A gram is a gram.
This is basic stuff. You must have calculated moles a million times by now. mols = grams/molar mass.
The vapor pressure of chloroform is 173.11 mm Hg at 25 degrees celsius. A nonvolatile, nonelectrolyte that dissolves in chloroform is aspirin. Calculate the vapor pressure of the solution at 25 degrees celsius when 6.243g of aspirin (180.1g/mol) are dissolved in 244.5g of chloroform.
Chloroform=119.40
I did 6.243g aspirin / 180.1g = 0.0346 moles
244.5g / 119.40g = 2.04 moles
Yes im sorry I am sort of confused. So is the total number of moles what they gave me in the problem, 6.243?
