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
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 ------------------

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.
A mixture of KCl and KNO3 is 44.20 percent potassium by mass the percentage of kcl in the mixture is?
To find the percentage of KCl in the mixture, we first need to determine the percentage of potassium coming from KCl. Since the mixture is 44.20% potassium by mass and KCl is 74.55% potassium by mass, we can set up a simple ratio to find the percentage of KCl in the mixture as (74.55% / 100%) * 44.20% = 32.97%. Therefore, the percentage of KCl in the mixture is approximately 32.97%.
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
How do you make 3 KCl solution?
To make a 3 M solution of KCl, you would need to dissolve 149.5 grams of KCl (potassium chloride) in enough water to make 1 liter of solution. Weigh out the desired amount of KCl, add it to a suitable container, and then add water while stirring until the KCl is completely dissolved.

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
Why do you use kcl for making salt bridge?
A salt bridge is used in electrochemical cells to allow for the flow of ions between the half-cells. Potassium chloride (KCl) is a commonly used salt for making salt bridges because it provides a source of mobile ions (K+ and Cl-) that can help maintain electrical neutrality in the half-cells by allowing the flow of ions to balance the charge buildup.
How do you convert mmol to milliequivalent for Kcl?
To convert mmol of KCl to milliequivalents, you need to know the valence of the ion. Since KCl contains K+ and Cl- ions with a 1:1 ratio, one mol of KCl is equal to one milliequivalent of K+. Therefore, the conversion factor between mmol and milliequivalents for KCl is 1 mmol = 1 mEq.
