Question

В 12% сахарный сироп, массой 300 г добавили 100 г сахара. Определите концентрацию раствора.

Answer 1

1) 300*0,12=36 г сахара в 12%-м сиропе

2) 36+100=136 г сахара во втором сиропе

3) 300+100=400 г - масса второго сиропа

4) 400 г - 100%

136 г - Х%

х=136*100:400=34%-й сироп получится

Answer 2

Calculation of Solution Concentration

To determine the concentration of the solution, we need to calculate the mass of the solute (sugar) and the total mass of the solution.

Given: - Mass of sugar syrup = 300 g - Mass of sugar added = 100 g

To calculate the total mass of the solution, we add the mass of the sugar syrup and the mass of the sugar added:

Total mass of the solution = Mass of sugar syrup + Mass of sugar added

Total mass of the solution = 300 g + 100 g = 400 g

The concentration of the solution can be calculated using the formula:

Concentration = (Mass of solute / Total mass of solution) x 100

Substituting the values:

Concentration = (100 g / 400 g) x 100

Concentration = 25%

Therefore, the concentration of the solution is 25%.
