All rights reserved.Explanation / Answer
tetrahydrofuran mass = 72gm /mol
benzene mass = 78 gm/mol
molefraction of benzene = 0.276 = no of moles of benzene / total no of moles
mass of1 mole of solvent = 0.276*78+0.724*72 = 73.656 gm
1 mole of the solvent contains 0.276moles of benzene and 0.724 moles of tetrahydrofuran
1 mole of the solvent contains 0.276moles of benzene
73.656 gm of solvent contain 21.528 gms of benzene
? gm of solvent contain 611 gms of benzene
2090.478 gm of solvent contain 0.611 kg of benzene
