Question

a solution is prepared by dissolving 18 g of sugar in 520 g of water what is the mass percentage of the solution

Answer 1

mass%=(mass of solute/mass of solution)×100
so,here mass of solute=18g and mass of solution=520g+18g=538g
Now,
mass%=(18/538)×100=>3.345%

Answer 2

mass%=(mass of solute/mass of solution)×100

so,here mass of solute=18g and mass of solution=520g+18g=538g

Now,

mass%=(18/538)×100=>3.345%
