How many moles of KCl would be dissolved in 4 liters of water to make 2 Molar solution?
8 moles of KCl are needed.
What is the molarity of a solution in which 0.751 moles of hcl are dissolved in 0.951 liters of solution?
0.751 mol/0.951 L = 0.790 mol/liter = 0.790 M
2.943g of pure sulphuric acid H2S4 is dissolved in water to make 150.0 cm3 of solution What is the concentration of the solution?
The concentration of a solution is moles/volume. 2.943g of pure sulphuric acid H2S4 is approximately 15 moles, and 15/150 cm3 is 10.
What is the molarity of a solution that contains 0.25 moles of solute in 0.50L of solution?
Molarity = moles of solute/volume of solution M = 0.25 moles/0.50L = 0.5M
How many moles of ions are released when 42.1g of CuSO4is dissolved in water?
The number of moles is 0,527.
What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
Moles of solute/ kg of solvent = 2 molal solution
What is the molality of a solution of 90 grams of glucose C6H12OSUB6 dissolved in 800 grams of water?
first determine the number ofmoles dissolved in given solution then .5 moles moles dissolved in 800g. as comparison with 1000g of water, we know 100g of water dissolve only.1 moles of a glucose so we .7moles of glucose dissolve in 800g.
How many total moles of KNO3 must be dissolved in water to make 1.5 liters of 2.0 M solutions?
Assuming you mean 2 M solution and not 2 m (molal), you would do it as follows:2.0 moles/L x 1.5 liters = 3.0 moles KNO3 must be dissolved in 1.5 liters.
What is the molarity of a solution which contains 2 moles of glycerin dissolved in 1000g of water?
Well the definition of molarity is how many moles in every litre. You already have your answer expressed as moles in a litre, approximately. Density is approximately 1000g per litre, therefore it will be approximately 2 molar. (You haven't expressed temperature, but density should remain close to 1).
What is the molarity of an aqueous solution that has 8.0 moles of solute dissolved in 4.0 liters solution?
M = 2.0 moles/ liter
Which solution is the most concentrated?
6 moles of solute dissolved in 4 liters of solution.
How do you calculate moles of NaCl are formed?
moles of NaCl in the solution = mass of dissolved NaCl/58,44
Number of moles of solute dissolved in 1 L of solution?
The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
What does 1M glucose solution mean?
1M glucose means that 1 mole of glucose is dissolved in 1kg of water. Since 1M means 1 molal. And molality is equla to no.of moles of solute per kg of water.
How many moles of surcose are dissolved in 250 ml of solution if the solution concentration is 0.150 M?
Molarity = moles of solute / liters of solution moles = Molarity x liters = 0.150 x .250 = 0.0375 moles
What is the molarity of a solution in which 0.597 moles of HCl are dissolved in 0.169 liters of solution?
Molarity = moles of solute/liters of solution Molarity = 0.597 moles HCl/0.169 liters = 3.53 M HCl ------------------
A flask contains 300.0cm3 of a 0.500 acid solution How many moles of the pure acid must have dissolved?
All of the moles of pure acid will have dissolved in the flask.
