Since you know the molecular mass of KCl is 74.55, that can be set up as a fraction:
74.55 grams/ 1 mole.
You want a 3 molar solution and (for simplicity sake) you want 1 Liter. This can be expressed as the fraction:
3 moles / 1 Liter
If you set these equations next to each other (find the product--multiply them), you can cancel out the units that exist on both the top and bottom, which in this case are the moles:
74.55 g / 1 mole * 3 moles/1 Liter =
74.55 g/1 * 3/1 Liter
Since the denominator is 1, this is really just 74.55 g * 3/Liter -or- 223.65 grams/Liter ("223.65 grams per Liter").

What should be the pH of 3M KCl solution?
I believe it should be 7.0. Here's an example of 3M KCl made for sale with the specs, showing a pH of 7.0
How much kcl require for prepaire 3M kcl?
Molar mass of KCl = 74.55g/mol.ie, if you dissolve 74.55g KCl in 1litre (1000 ml) of water, it will be 1M KCl solution.If you want to make 3M KCl solution,Dissolve 3 ×74.55 = 223.65g KCl in 1litre (1000 ml) of water.If you want to make different molar solutions of KCl, just calculate as per below given equation.Weight of KCl to be weighed =Molarity of the solution needed × Molecular weight of KCl (ie, 74.55) × Volume of solution needed in ml / 1000.To prepare 3M KCl in 1 litre, it can be calculated as follows,3 mol × 74.55 g/mol × 1000 ml / 1000 ml = 223.65gByPraveen P Thalichalam, Kasaragod (Dist), Kerala.
How many grams of KCl to make 50 mL of 2.45 M KCl?
9.13
Why pH probes always kept immersed in 3M Kcl solution?
I just got done talking with a vendor for pH probes and he explained that the KCl solution helps facilitate the measurement of the hydrogen ions with the electrode. It will actually seep out in small quantities from the tip which is a membrane.
How many grams of KCl are needed to make 100 ml of a 3.5M solution?
In a 3.4 M solution, there are 3.4 moles per liter. If you want to make 3 liters of solution, you'll need 3 liter * 3.4 moles/liter = 10.2 moles The molar mass of KCl is 39.098 g/mole K + 35.453 g/mole Cl = 74.551 g/mole KCl To get the number of grams, multiply the number of moles by the molar mass: 10.2 moles * 74.551 g/mole KCl = 760.4202 g = 0.760 kg

What volume of 12.0M KCl is required to make 300.0 ml of 0.50 M KCl?
In order to make 300.0 ml of 0.50 M KCl you need 0.300 L x 0.50 M = 0.150 moles KCl. To make 0.150 moles of 12.0 M KCl you need 0.150 moles / 12.0 M = 0.0125 L = 12.5 ml.
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 to make KCl 1 M?
Dissolve 74,5513 g dried KCl in 1 L distilled water, at 20 oC.
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 do you make 3m a day in Runescape?
The fastest way to make 3m in about a hour or more is green dragons there bones went up to 5k now,that's how i make millions.

Is there any pH change when KCl dissolves in water?
No there is no pH change KCl+H20--> K2O + HCl neither OH- or H+ is formed, which would make it either more acidic or more basic. KCl is a salt
