The observed depression in freezing point of water for a particular solution in ` 0.093^(@) k ` calculate the concentration of the solution in molality Given that molal depression constant for water is ` 1.86 K KG mol ^(-1 ) `

Explanation

`Delta T _(f) = 0.093^(@)C = 0.093 K, m = ` ?
`K _(f) = 1. 86 K kg mol ^(-1)`
` Delta T _(f) = K _(f) .m`
`therefore m = (Delta T _(f))/( K _(f)) = (0.093K)/(1.86 K kg mol ^(-1)) = 0.05 mol kg ^(-1) = 0.05 m`
