1.	if solution of sucrose in water is labed as 20%w/W.Caliculate mole fraction of each componrnt in the solution.
Answer» 20% w/w solution of sucrose in water means that 20 g of sucrose in present in 100 g of the solution i.e., 20 g of sucrose is present in (100 - 20) g = 80 g of water. Mole fraction of sucrose (x_s) = 0.2 / ( 0.2+0.8) = 0.2 And, mole fraction of water (x_w)= 1 - x_s =1-0.2 =0.8

Answer»

20% w/w solution of sucrose in water means that 20 g of sucrose in present in 100 g of the solution i.e., 20 g of sucrose is present in (100 - 20) g = 80 g of water.

Mole fraction of sucrose (x_s) = 0.2 / ( 0.2+0.8) = 0.2

And, mole fraction of water (x_w)= 1 - x_s

=1-0.2

=0.8
