Answer 2

Calculation of Sugar Concentration in the Solution

To find the concentration of sugar in the solution, we need to determine the mass of sugar and the mass of water in the given ratio.

The given ratio is 22:3, which means that for every 22 units of water, there are 3 units of sugar. Let's assume that the mass of water is 22x and the mass of sugar is 3x, where x is a constant.

According to the given information, the ratio of the mass of water to the mass of sugar is 22:3. Therefore, we can set up the equation:

22x / 3x = 22 / 3

Simplifying the equation, we find that:

x = 3

Now, we can calculate the mass of water and the mass of sugar in the solution:

Mass of water = 22x = 22 * 3 = 66 units Mass of sugar = 3x = 3 * 3 = 9 units

Therefore, the mass of water in the solution is 66 units, and the mass of sugar in the solution is 9 units.

To find the concentration of sugar in the solution, we divide the mass of sugar by the total mass of the solution and multiply by 100 to express it as a percentage:

Concentration of sugar = (Mass of sugar / Total mass of solution) * 100

Total mass of solution = Mass of water + Mass of sugar = 66 + 9 = 75 units

Substituting the values into the equation, we get:

Concentration of sugar = (9 / 75) * 100 = 12%

Therefore, the concentration of sugar in the solution is 12%.
