Household vinegar is acqueous 5.00%,acetic acid solution(by mass),if its density is 1,01 g/ml.calculate the mole fraction!molarity,and molality of the solution.
5.00% acid means 5g acid/100 g soln.
5g/molar mass acetic acid = mols.
Use density to convert 100 g to volume
Then M = mols/L soln.
Can you take it from here?
