|
Answer» ality of the solution is 1.02 M.Accurate Question :CALCULATE Molality of 9.8% (w/w) solution of sulphuric acid . If the density of the solution is 1.02 g/ml.Explanation :GIVEN :Density of the solution - 1.02 g/ml.Molar mass of - 98 g/ mol.Mass of - 9.8.Mass of solution - 100 grams.9.8% (w/w) solution of sulphuric acid.This implies that - 9.8 grams of is present in 100 gram of solution.To Find :The Molality.We KNOW that :So,The volume of the solution :The number of moles :Putting values, |
