How to prepare 0.1 KOH solution?
Take 5.7g of KOH and dissolve in 1dm of water
How do you prepare 30 percent of methanolic KOH solution?
Dissolve 30 g KOH in 100 mL methanol.
How many grams of solid KOH is necessary to prepare 220.0 ml of 0.500 M KOH solution?
Molarity = moles of solute/Liters of solution ( 220.0 ml = 0.220 Liters ) 0.500 M KOH = moles KOH/0.220 Liters = 0.110 moles KOH (56.108 grams/1 mole KOH) = 6.17 grams solid KOH needed
How will you prepare 500ml of 1N KOH solution?
You weight 14,5 gramm KOH in a bottle and than fill that bottle with deionized water till it holds 500ml.

How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
Molarity = moles of solute/liters of solution ( 300 ml = 0.300 liter ) 0.250 molar KOH = moles KOH/0.300 liters = 0.075 moles KOH
How many grams of koh are needed to prepare 250 milliliters of a 2 m solution of koh formula mass 56?
28 gram. = 2 * 56 * 250 / 1000
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?
How many moles of KOH are contained in 750. mL of 5.00 M KOH solution?
Molarity = moles of solute/volume of solution 0.500 M KOH = moles KOH/125 ml 62.5 millimoles, or to answer the question precisely, 0.0625 moles KOH
Why do we use KOH in saponification reaction?
KOH is used to prepare liquid soaps.
How many grams of solid KOH is necessary to prepare 60ml of 2M KOH solution?
Moles KOH = Molarity x Volume = 0.214 moles/liter x 0.0602 liters = 0.0129 moles KOH. Remember, 60.2 mL = 0.062L
Why alcohol is required in koh solution?
because KOH is hygroscopic
How do you make a 1 percent aqueous solution of potassium hydroxide?
1% solution of KOH contains 1g of KOH in 100g of solution. This means that you need to mix 1g of KOH and 99g of water.
