The Total solution for NCERT class 6-12
A solution of glucose in water islabelled as 10% w/w, what would be the molality and mole fraction of eachcomponent in the solution? If the density of solution is 1.2 g mL−1,then what shall be the molarity of the solution?
10% w/w solution of glucose inwater means that 10 g of glucose in present in 100 g of the solution i.e., 10 gof glucose is present in (100 − 10) g = 90 g of water.
Molar mass of glucose (C6H12O6)= 6 × 12 + 12 × 1 + 6 × 16 = 180 g mol−1
