What is the molarity of a solution prepared by dissolving 2.41 g of potassium iodide KI in 100 mL of water?
Find moles potassium iodide first.2.41 grams KI (1 mole KI/166 grams) = 0.01452 moles KIMolarity = moles of solute/Liters of solution ( 100 ml = 0.1 Liters )Molarity = 0.01452 moles KI/0.1 Liters= 0.145 M KI solution================
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
What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?
The molarity of a solution given by the number of moles divided by the volume it contains. Hence, the molarity of KCl is 4.00/3.00 = 1.33 mol/L.
How many milliliters water are needed to make a 0.171 M solution that contains 1.00 g of NaCl?
1 gram NaCl (1 mole NaCl/58.44 grams) = 0.0171 moles NaCl Molarity = moles of solute/volume ( liters) of solution 0.171 M = 0.0171 moles NaCl/volume 0.1 Liters, or more to our point; 100 milliliters
Hoy many moles of potassium nitrate are produced when 2 moles of potassium phosphate react wth 2 moles of aluminum nitrate?
there are two moles produced in potassium nitrate.
What is the molarity of a potassium carbonate solution if 4.8 mol is dissolved in 1.6L?
You have 4.8 moles and this is in 1.6 litres. 4.8 moles / 1.6 is 3 moles. This is also now 3 molar.
How many grams of potasium carbonate are in 1.5 moles of this substance?
1,5 moles of potassium carbonate have 276,41 g.
What is the number of moles os H2SO4 in 100mL of 12M H2SO4 solution?
The answer is 1,2 mol.
How many moles ok potassium are present in 343 mL of a 1.27 M solution of potassium phosphate?
The amount of potassium phosphate in the solution is 1.27 M * 0.343 L = 0.43561 moles.The chemical formula of potassium phosphate is K3PO4, so there is three times as many moles of potassium as there are moles of potassium phoshate in the molecule:0.43561 * 3 = 1.30683Answer: 1.31 moles
How many moles of potassium hydroxide are required to make 200cm3 of 0.5M solution?
0.1 moles
How many moles of kbr are present in 25ml of a 1.5 M solution?
Molarity = moles of solute/Liters of solution ( 25 ml = 0.025 Liters ) 1.5 M KBr = moles KBr/0.025 Liters = 0.038 moles potassium bromide ------------------
What is the molar concentration of K ions in a 0.0175 M solution of potassium phosphate?
0,052 moles
The volume in ml of 2.26m potassium hydroxide solution that contains 8.42g of solute?
8.42 grams of KOH is equal to 0.15 moles. If the solution has a molarity of 2.26 moles per liter, then there are 66.4 milliliters of solution.
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.
