What is the volume of 1.90 mol of NaOH and its concentration is 0.555 M?
Molarity = moles of solute/Liters of solutionLiters of solution = moles of solute/MolarityLiters NaOH = 3.25 moles NaOH/2.5 M NaOH= 1.30 Liters NaOH=============
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
What will be the molarity for a solution prepared by dissolving 50 grams of KOH in 700ml of water?
Molarity= Number of moles of solute/Liters of solution 50 grams KOH 700 ML to .7 Liters of h2o Molar Mass of KOH= 56 50 divided by 56 = .89 moles Molarity= .89 mol/.7 L = 1.27 MOLARITY
An acid solution is 0.120 m in hcl and 210 m in h2so4 what volume of a 150 m koh solution would have to be added to 500.0 ml of the acidic solution to neutralize completely all of the acid?
i have no freaking idea.
Why use ethanolic KOH?
ethanolic KOH can precipitate the impurities in solution
What is the volume of 1.90 mol of NaOH and its concentration is 0.555 M?
Molarity = moles of solute/Liters of solutionLiters of solution = moles of solute/MolarityLiters NaOH = 3.25 moles NaOH/2.5 M NaOH= 1.30 Liters NaOH=============
Why freshly prepared 'KOH' solution is taken in a watch-glass and kept in the bell jar during the experiment to show that carbon-dioxide is essential for photosynthesis?
It is because 'KOH' solution helps to absorb all the carbon dioxide present in the bell jar.
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
How do you make 0.1m KOH?
An 11 M KOH solution indicates there are 11 moles of KOH per liter of water. 1 mole of KOH has a volume of 27.4 mL, so to account for the added volume it is necessary to add 15.75 moles of KOH per liter of water, or 884 grams per liter.
Why alcohol is required in koh solution?
because KOH is hygroscopic
What will be the molarity for a solution prepared by dissolving 50 grams of KOH in 700ml of water?
Molarity= Number of moles of solute/Liters of solution 50 grams KOH 700 ML to .7 Liters of h2o Molar Mass of KOH= 56 50 divided by 56 = .89 moles Molarity= .89 mol/.7 L = 1.27 MOLARITY
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.
What is the molarity of a solution when 50.0ml of a 4.00M KOH solution is diluted to 200ml. what is the percent concentration of KOH in this final solution. asume the density of 1.0gmole?
The concentration is 1 mol/L or 5,611 g KOH/100 mL solution.
How do you make 5 percent potassium hydroxide solution?
A solution that is refered to as a percentage of something (like potassium hydroxide, KOH) refers to the mass of the solute compared to the total solution, so a 5% KOH solution would be 5g KOH + 95g H2O, and the 5g KOH would be 5% of the 100g total of the solution.
How many grams of KOH are present in 31.5 mL of a 7.26M KOH solution?
The answer is 12,831 g KOH.
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
An acid solution is 0.120 m in hcl and 210 m in h2so4 what volume of a 150 m koh solution would have to be added to 500.0 ml of the acidic solution to neutralize completely all of the acid?
