Question

5. 300 gms of sugar solution has 40% sugar in it.
How much sugar should be added to make it 50%
in the solution?
how you took 120​

Answer 1

Answer:

Mass/ Mass percentage =

 mass of solute $\frac{mass of solute}{mass of solution}$ x 100

 in 40% sugar in sugar solution

   we get

$\frac{x}{300}$ x 100 = 40%

$x$ = 120 gm

In 50 % we get

$\frac{y}{300}$ x 100 = 50%

$y$ = 150m

40% = 120 gm

50% = 150 gm

  150 -120= 30 gm
