How do you make a 20% glucose solution?
Last Updated: 5th June, 2021
- Measure out 1.5L of DI water into 2L flask on hot plate.
- Add stir bar and begin spinning.
- Measure out 400g of glucose powder.
- Stir until dissolved.
- Bring total volume up to 2L using 2nd graduate cylinder.
- Add back to flask for mixing.
- Dispense 100mL of glucose solution into 20 100mL glass bottles.

In this regard, how do you make a 1% glucose solution?
To work out how much glucose you need to make a solution of a given percent, multiply (mass/volume) by volume, bearing in mind that 1 g in 100 ml is a 1 percent solution. For this example, if you want to make a total solution of 500 ml of 20 percent glucose, multiply (20/100) by 500.
Also, what is a 20% solution? 20% by mass means 20 g of the NaOH is dissolved in 100 g of solution. What is the meaning of 20% mass by volume solution? 20% mass by volume means 20 g of the NaOH is dissolved in 100 mL of the solution.
In this way, how do you make a glucose solution?
- Weight out 20g of glucose (dextrose)
- Add to 70ml of H2O.
- Dissolve by stirring. May use some heat.
- Once the sugar has dissolved, bring the volume of the mix up to 100ml total.
How do you make a 10% sucrose solution?
Dissolve 10 grams sugar in 80 ml water. After the sugar is completely dissolved, adjust the volume to 100 ml. 10% sugar and 90% water by mass.
