Question

При смешивании 100г 10% раствора и 200 г 20%получили новый раствор. Найти его массу. Срочно на завтрашний день!!!!

Answer 1

100+200=300г общая масса р-ра
100*0,1+200*0,2=10+40=50г глюкозы в двух р-рах
50/300*100%=16,6%

Answer 2

Problem Statement

You have two solutions: one is a 10% solution weighing 100g, and the other is a 20% solution weighing 200g. When you mix them together, you obtain a new solution. You need to find the mass of this new solution.

Solution

To find the mass of the new solution, we can use the concept of the conservation of mass. The total mass of the new solution should be equal to the sum of the masses of the two original solutions.

Let's calculate the mass of the new solution:

1. Calculate the mass of the first solution: - Mass of the first solution = 100g

2. Calculate the mass of the second solution: - Mass of the second solution = 200g

3. Calculate the total mass of the new solution: - Total mass of the new solution = Mass of the first solution + Mass of the second solution

Therefore, the mass of the new solution is 300g.

Conclusion

The mass of the new solution obtained by mixing 100g of a 10% solution and 200g of a 20% solution is 300g.
