How many grams of starch would you need to make 500ml of a 5% solution?

- 25 grams.
Solution:- We are asked to make 500 mL of 5% glucose solution. The percentage is the mass by volume percentage. 5% glucose solution means 5 grams of glucose present in 100 mL solution. From this given information, we can easily calculate the mass of glucose required to make 500 mL solution.
The calculations are shown as:

500mL*5g/100mL

= 25g
So, 25 grams of glucose are required to make 500 mL of 5% solution.
