How do you make a 2M glucose solution?

Prepare 2M glucose solution : – Dissolve 18 g glucose into 50 ml (final volume) ddH2O and filter-sterilize into a sterile 50 mL tube under the hood PSM.

How many glucose molecules are present in a sample of a 1 M solution of glucose?

1 litre of 1M solution contains one mole (6.02 × 1023) molecules of glucose.

How would you make a 0.5 molar solution of sucrose?

Explanation:

  1. Calculate the moles of sucrose. nsucrose=10g ×1 mol342.30g =0.0292 mol.
  2. Calculate the volume of the solution. V=0.0292mol ×1 L0.5mol =0.058 L = 58 mL.
  3. Calculate the mass of the solution.
  4. Calculate the volume of the water.
  5. Calculate the molal concentration of the sucrose.
  6. Calculate the mole fraction of water.

How many grams of the molecule glucose C6H12O6 would be required to make 1 l of a 0.5 M solution of the molecule?

e molar mass of glucose (C6H12O6) is 180 g/mol. Which of the following procedures should you carry out to make a 0.5 M solution of glucose? Dissolve 90 g of glucose in a small volume of water, and then add more water until the total volume of the solution is 1 L.

How many molecules are in a gram of glucose?

Assuming you are talking about table sugar, sucrose, which has a molar mass of 342.2965g/mol you would do 1.000g divided by 342.2965g/mol to get the moles of sugar. Then multiply that number by 6.022 x 10²³ which is 1.759×10²¹ molecules, or 1,759,000,000,000,000,000,000 molecules.

How many molecules are in a liter of glucose?

0.5 mole/liter x 180 grams/mole x 1 liter = 90 g. ✍ How many molecules of glucose are in that 1 liter of 0.5M glucose solution? 0.5 mole/liter x 1 liter x 6.023×1023 molecules/mole = 3.012×1023 molecules.

How to calculate the number of moles of glucose?

In above glucose sample, the no. of glucose molecules = 0.01 x 6.022 x 10 23 = 6.022 x 10 21. Remember that one mole of any substance contains Avogadro number of particles (may be atoms or molecules or ions etc.). If the substance is molecular, the number molecules will be equal to 6.022 x 10 23.

How many oxygen atoms are in one molecule of glucose?

From the molecular formula, C6H12O6, one can find there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in one molecule of glucose.

What is the Avogadro number of atoms in a mole?

Remember that one mole of any substance contains Avogadro number of particles (may be atoms or molecules or ions etc.). If the substance is molecular, the number molecules will be equal to 6.022 x 10 23. If we take atomic substance, then the number of atoms in one mole is equal to Avogadro number.
