A sugar solution with concentration 8.5% (w/w) is made bydissolving 'X

1.	A sugar solution with concentration 8.5% (w/w) is made bydissolving 'X'g of sugar in 450 g of water. The amount 'X' is49.2 g45.3 g41.80 g35 g
Answer» Given:- •MASS of water(solvent)=450g •Concentration of the solution=8.5% •Mass of SUGAR(solute)=Xg To find:- •Mass of sugar or value of X Solution:- Mass of the solution=450+X We know that----- =>Concentration of solution=Mass of solute/Mass of solution×100 =>X/450+X×100=8.5 =>100X/450+X=8.5 =>100X=8.5(450+X) =>100X=3825+8.5X =>3825=100X-8.5X =>3825=91.5X =>X=3825/91.5 =>X=41.80g Thus,the amount 'X' is 41.80g.

Answer»

•MASS of water(solvent)=450g

•Concentration of the solution=8.5%

•Mass of SUGAR(solute)=Xg

•Mass of sugar or value of X

Mass of the solution=450+X

We know that-----

=>Concentration of solution=Mass of solute/Mass of solution×100

=>X/450+X×100=8.5

=>100X/450+X=8.5

=>100X=8.5(450+X)

=>100X=3825+8.5X

=>3825=100X-8.5X

=>3825=91.5X

=>X=3825/91.5

=>X=41.80g

Thus,the amount 'X' is 41.80g.
