Question

Convert a 0.25 mol/kg sucrose solution into percent by weight. The density of the solution isb1.2 g cm^-3.

Answer 1

Answer #1

molar mass of sucrose (C12H22O11) = 342g/mole

mass of sucrose solution = 0.25mole/Kg * 342g/mole = 85.5g/Kg

85.5g/Kg sucrose solution means 85.5g of sucrose present in 1kg(1000g) of solution

percent by weight = 85.5*100/1000 = 8.55% >>>answer

Answer 2
