What is the molarity of a solution that contains .202 mol KCI in 7.98 L of solution?
Molarity = moles of solute/Liters of solution Molarity = 0.202 moles KCl/7.98 Liters = 0.253 M KCl solution ================
How many grams of KCl are needed to prepare 125 mL of a 0.720 M KCl solution?
The answer is 6,71 g dried KCl.
How do you prepare a 0.01 solution in 100ml?
Depend on the kind of concentration it is expressed in. For a 1. 0.001 Molar solution, dissolve 0.001 mols of solute in enough solvent to obtain 1L of solution 2. 0.001 molal solution, dissolve 0.001 mols in 1kg of solution.
When 5 grams of KCl are dissolved in 50. grams of water at 25C the resulting mixture can be described as?
This is a solution of 10 g KCl/100 g water.
How would you make a 500 ml solution of 1.0 M KCl?
Take 37.25g of KCl exactly and dissolve in 500ml of water
How many grams of KCl are required to prepare 2.25L of a 0.75m KCl solution?
Molarity = moles of solute/Liters of solution 0.75 M KCl = moles KCl/2.25 Liters = 1.6875 moles KCl (74.55 grams/1 mole KCl) = 126 grams of KCl needed
How you prepare 3 M KCl solution?
Weigh 22.35 grams of KCl and Dissolve in 100 mL of Distilled Water
How many moles of KCl are needed to prepare 1.00 L of a 1.0M KCl solution?
M= moles in solution/liters so plug in what you know 3.0M of KCl solution = moles in solution/ 2.0L multiply both sides by 2.0L moles solute = 1.5 moles KCl so you need 1.5 moles KCl to prepare the solution
How many moles of KCL are present in 50.0ml of a 0.552 M solution?
Molarity = moles of solute/Liters of solution ( 50.0 ml = 0.05 Liters ) 0.552 M KCl = moles/.0.05 liters = 0.0276 moles of KCl
What is the molarity of a solution made by dissolving 4.88 g of KCl in 423 mL of solution?
Need mole KCl first. 4.88 grams KCl (1 mole KCl/74.55 grams) = 0.06546 moles KCl =======================now, Molarity = moles of solute/Liters of solution ( 423 ml = 0.423 Liters ) Molarity = 0.06546 moles KCl/0.423 Liters = 0.155 M KCl ------------------
What is the molarity of a solution that contains .202 mol KCI in 7.98 L of solution?
Molarity = moles of solute/Liters of solution Molarity = 0.202 moles KCl/7.98 Liters = 0.253 M KCl solution ================
How many grams of KCl are needed to prepare 125 mL of a 0.720 M KCl solution?
The answer is 6,71 g dried KCl.
What is the molarity of a solution that contains 0.202 moles KCl in 7.98 liters of solution?
The molarity is 0,025.
How will prepare the 0.1N of KCL solution?
0.1 N KCl is the same as 0.1 M KCl. This requires one to dissolve 0.1 moles per each liter of solution. The molar mass of KCl is 74.6 g/mol. So 0.1 moles = 7.46 gDissolve 7.46 g KCl in enough water to make 1 liter (1000 ml)Dissolve 3.73 g KCl in enough water to make 0.5 liter (500 ml)Dissolve 0.746 g KCl in enough water to make 0.1 liter (100 ml)etc., etc.
How much 75.66MKCL is required toprepare 1L of solution?
I did not know that you could get a concentration of 75.66 M KCl, but; Molarity = moles of solute/Liters of solution 75.66 M KCl = moles KCl/1 liter = 75.66 moles of KCl 75.66 moles KCl (74.55 grams/1 mole KCl) = 5640 grams KCl that is about 13 pounds of KCl in 1 liter of solution. This is why I think there is something really wrong with this problem!
How do you prepare a 0.01 solution in 100ml?
Depend on the kind of concentration it is expressed in. For a 1. 0.001 Molar solution, dissolve 0.001 mols of solute in enough solvent to obtain 1L of solution 2. 0.001 molal solution, dissolve 0.001 mols in 1kg of solution.
What color is KCl in water?
the solution of KCl looks like a clear water with little tint of gray swirls
