How much glucose would be required to prepare 200 mls of a 5 % solution of glucose?

To prepare a 5% glucose solution, you need 5g of glucose for every 100ml of solution.

Step 1: Identify the required concentration. In this case, it's 5% glucose. This means that in every 100ml of solution, 5g of glucose is present.

Step 2: Determine the total volume of the solution needed. In this case, it's 200ml.

Step 3: Since the concentration is given per 100ml, we need to find out how many "100ml"s there are in 200ml. So, we divide 200ml by 100ml, which gives us 2.

Step 4: Multiply the number of "100ml"s by the amount of glucose needed per "100ml". So, 2 * 5g = 10g.

Therefore, to prepare 200ml of a 5% glucose solution, 10g of glucose is required.
