Mixed 100 g of a 10% solution and 200 g of a 5% glucose solution. What is the mass fraction (percentage) of carbohydrate in the resulting solution?
To determine the final glucose concentration after mixing two different solutions, use the formula.
W (in-va) = w1 • m1 + w2 • m2 / m1 + m2.
W (glucose) = 10% • 100 g + 5% • 200 g / 100 g + 200 g = 6.67%.
The concentration of carbohydrate in the resulting solution will be 6.67%, and the mass is 300 g.
