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?


  1. Weight out 20g of glucose (dextrose)
  2. Add to 70ml of H2O.
  3. Dissolve by stirring. May use some heat.
  4. Once the sugar has dissolved, bring the volume of the mix up to 100ml total.
  5. Autoclave.

How do you make a 10% sucrose solution?

What is a 1% solution?

A one percent solution is defined as 1 gram of solute per 100 milliliters final volume. For example, 1 gram of sodium chloride, brought to a final volume of 100 ml with distilled water, is a 1% NaCl solution. To help recall the definition of a 1% solution, remember that one gram is the mass of one milliliter of water.

What is a 1 1 solution?

1:1 is just a common way to express the composition of a solution. In this case mixing equal amount of two components. Most of the time they mean volume but sometimes it's weight. E.g. a 1:1 MeOH:water (v/v) solution is made by mixing an equal volume of water with methanol.

How do you find the concentration of glucose?

Determine the concentration of glucose in each Kool-Aid sample either by calculating it or using the graph. To calculate it, divide its absorbance by the slope of the standard curve. If you did not have to redraw the standard curve graph, you can find the slope of the standard curve in the equation of a line.

What is diluent volume?

A dilution solution contains solute (or stock solution) and a solvent (called diluent). Multiply the final desired volume by the dilution factor to determine the needed volume of the stock solution. In our example, 30 mL x 1 ÷ 20 = 1.5 mL of stock solution.

What is a 1/10 dilution?

For example, to make a 1:10 dilution of a 1M NaCl solution, you would mix one "part" of the 1M solution with nine "parts" of solvent (probably water), for a total of ten "parts." Therefore, 1:10 dilution means 1 part + 9 parts of water (or other diluent).

Is 20 sucrose solution hypertonic?

The sucrose solution is hypertonic to the water – it is a more concentrated solution. A less concentrated solution is hypotonic to a more concentrated solution, while two solutions at the same concentration are isotonic.

How do you get 10% HCl from 37 %?

Re: Preparing 10% HCl
In 37% conc HCl,mass of HCl in 1000ml=1.19g/ml x1000ml x37%=440.3g. mass of HCl in 100ml=44.03g. 10/44.03 x 100ml = 22.7ml of conc HCl. Add water to make up to 100ml to get 10%w/v HCl.
