Final answer:
To find out how much vitamin C is in 25mL, you need to know the concentration of vitamin C in the solution. If the concentration is 60 mg per 100 mL, then the amount of vitamin C in 25 mL would be 15 mg.
Step-by-step explanation:
To find out how much vitamin C is in 25mL, you need to know the concentration of vitamin C in the solution.
For example, if the concentration of vitamin C is 60 mg per 100 mL, you can calculate the amount of vitamin C in 25 mL using the following equation:
Amount of vitamin C = (Concentration of vitamin C / 100) x Volume of solution
Substituting the values into the equation, we get:
Amount of vitamin C = (60 mg / 100 mL) x 25 mL = 15 mg
