Q:My grandmother made kool-aid with 120 g of sugar (Sucrose) per liter. Assuming that the liqiud portion is water (1g/ml)- What percent sucrose solution was my grandmothers Kool-Aid?
A: What i thought was that 120 g x1 mL/1g = 120 mL x100 = 12%. Is this right?
To determine the percent sucrose solution in your grandmother's Kool-Aid, you need to calculate the ratio of the mass of sucrose to the total mass of the solution and express it as a percentage.
First, you need to know the total mass of the solution. Since it is mentioned that the liquid portion is assumed to be water and its density is 1g/ml, you can use the volume (in milliliters) as the total mass (in grams).
In this case, the total mass of the solution is 1 liter, which is equivalent to 1000 mL.
Next, you need to calculate the percentage of sucrose in the solution. The formula to calculate the percent solution is:
% Sucrose = (mass of sucrose / total mass of solution) x 100
So, using your calculation method:
Mass of sucrose = 120 g
Total mass of solution = 1000 g
% Sucrose = (120 g / 1000 g) x 100 = 12%
Therefore, your calculation is correct, and your grandmother's Kool-Aid is a 12% sucrose solution.
