Let us start of with an assumption: we have ten moles of the given solution. Therefore we have 2 moles of iodine dissolved in 8 moles of benzene.

Molecular mass of benzene=78.

Molality=๐‘๐‘œ.๐‘š๐‘œ๐‘™๐‘’๐‘ ๐‘œ๐‘“๐‘–๐‘œ๐‘‘๐‘–๐‘›๐‘’/๐‘€๐‘Ž๐‘ ๐‘ ๐‘œ๐‘“๐‘ ๐‘œ๐‘™๐‘ฃ๐‘’๐‘›๐‘ก๐‘–๐‘›๐‘˜๐‘”

Therefore 8 moles of benzene weighs 78โˆ—8=624grams

Molality=(2โˆ—1000)/624 =3.205
