Toluene, C6H5CH3, is a liquid similar to benzene, C6H6. It is the starting material for other substances, including trinitrotoluene (TNT). the molality of toluene in a solution that contains 26.2 g of toluene and 132 g of benzene.
Calculate the molar fraction of toluene and benzene from the previous exercise. ?
n toluene = grams/molar mass
n benzene = grams/molar mass.
totl N = n toluene + n benzene
Xtolune = n toluene/total mols.
Xbenzene = n benzene/total mols.
