A solution of sugar is obtained by mixing 200 g of its 25% solution and 500 g of its 40% solution (both by mass). The mass percentage of the resulting sugar solution is ___________ (Nearest integer)

Step-by-Step Verified Solution

Let's first calculate the amount of sugar in each of the solutions :

  1. In the 25% sugar solution, the amount of sugar is 25% of 200 g, which equals 50 g.

  2. In the 40% sugar solution, the amount of sugar is 40% of 500 g, which equals 200 g.

Now, let's mix these two solutions together:

The total amount of sugar in the combined solution is 50 g (from the 25% solution) + 200 g (from the 40% solution) = 250 g.

The total weight of the combined solution is 200 g (of the 25% solution) + 500 g (of the 40% solution) = 700 g.

Therefore, the mass percentage of sugar in the combined solution is =250700×100 = 35.71%

Rounding to the nearest integer gives 36%. So, the mass percentage of the resulting sugar solution is 36%.
