Final answer:
To make a 25% solution of glucose of 200 g, we need 50 g of glucose and 150 g of water.
Step-by-step explanation:
To calculate the mass of glucose and the mass of water required to make a 25% solution of glucose, we need to understand what a 25% solution means. A 25% solution means that 25 g of glucose is dissolved in every 100 g of solution. So, if we want to make a 200 g solution, we can calculate the mass of glucose and water as follows:
- 25% of 200 g is equal to (25/100) x 200 g = 50 g of glucose.
- The remaining mass of the solution, which is 200 g - 50 g = 150 g, must be water.
Therefore, the mass of glucose required is 50 g, and the mass of water required is 150 g.
