What is the molality of solution consisting of 33.0 mL of benzene (C_(6)H_(6),d=0.877 g mL^(-1)) in 187 mL of hexane (C_(6)H_(14), d= 0.660 g ml^(-1))?

Answer»


SOLUTION :Mass of BENZENE = `33 xx 0.877` g
Mass of benzene `=(28.941)/78 = 0.371`
Mass of hexane `=187 xx 0.66 = 123.42`g
`m=(0.371 xx 1000)/(123.42) = 3.006`
