The molecular weight of glucose is 180. Let's say that you intend to make 100 ml of 5M solution. Here is the formula that can help you out every time you are dealing with molarity. (X, which is the desired weight divided by the molecular weight) X (1000/100, which is the desired volume) = 5, which is the desired molarity.
So, X/180 X 1000/100 = 5; then X = 90.
You need 90 g of glucose to make a 5 M of 100 ml solution of glucose.
Hope this is clear,

What is the morality of a solution that has 3 mol of glucose in 6kg of water?
Molarity (M) = mol solute /L solvent mol solute = 3 mol glucose L solvent = 6kg water = 6L water 3mol/ 6L = .5M
How many milliliters of 3M phosphoric acid H3PO4 can be made from 95ml of a 5M H3PO4 solution?
We need 158,3 mL HrPO4 5M.
What volume of a 3m koh solution can be prepared by diluting 0.5 l of a 5m koh solution?
What volume(L) of 3M KOH solution can be perpared by diluting 0.5 L of %M KOH solution?
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
5 N H2SO4 What is percent?
If you are asking what percent of H2SO4 that you have, I would need to know that volume of the 5M H2SO4
How many grams of KCl would you need to make 250 ml of a 5 M solution?
MW 74.5, 1M solution requires 74.5g in 1L, 5M solution requires 74.5x5 = 372.5g in 1 L. You would need 93.1g KCL to make 250mL 5M solution
What is the solution to 5m equals 40?
5m = 40m = 40/5m = 8
How would you prepare 30mL of a 5M NaCl solution from a 2M NaCl stock solution?
You have to evaporate (by open boiling) 45 mL of the 75 mL 2M NaCl solution thus reducing the volume to 30 mL 5M NaCl.
How can you make solution of 2M of 800 ml from 5M solution?
In order to have a 2M solution is means that you have 2 moles for every 1 liter. Because you only want to make 800mL of this solution you only need (0.8*2) moles of or 1.6 moles of the compound in your solution. This 1.6 moles is coming from your 5M solution. So how much 5M do you need to take out to have 1.6 moles. A 5 molar solution has 5 moles for every liter, since you only need 1.6 moles of it that you need(1.6/5) liters of the solution or 0.32 liters (320 mL). Calculations done. So your going to take 320 mL of the 5M solution and put it into an 800mL volumetric flask and add water up to the line, or to be more exact, add exactly 460 mL of water in order to dilute the solution from 5M to 800mL of 2M solution.
What would happen if you placed an artificial cell with 5M glucose in a beaker with pure water?
A solution which has a high concentration of a solute (example - glucose) will have a low water concentration. But when you look at pure water it has a high water concentration. So if a cell contains a high concentration of glucose and was placed in a pure water solution, water would simply move down its concentration gradient (going from high to low) which eventually causes the cell to swell. I hope this helped :D
What is the morality of a solution that has 3 mol of glucose in 6kg of water?
Molarity (M) = mol solute /L solvent mol solute = 3 mol glucose L solvent = 6kg water = 6L water 3mol/ 6L = .5M
How many grams of KMnO4 should be used to prepare 2L of a 5M solution?
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
PH of a 7.2x10-5M solution?
The pH is 4,14.
How many milliliters of 3M phosphoric acid H3PO4 can be made from 95ml of a 5M H3PO4 solution?
