The Molarity is equal to the number of moles divided by the liters.
M=mol/L
M=0.120 mol/5.0 L
M=0.024
so the molarity is 0.024 M

How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------

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 ================
What is the molarity of a solution that contains 6.42 moles of lithium nitate in 1.75 liters of solution?
Molarity is moles of solvent divided by liters of solution, so 6.42 / 1.75 = 3.67M.
What is the molarity of a solution that contains 31.0 grams of HCl in 500cm3 of solution?
31 grams HCl (1mol/36.458g ) = 0.850 moles 500cm^3 = 0.50 Liters Molarity = moles of solute/liters of solution Molarity = 0.850mol/0.50L = 1.7 Molarity
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.

The answer is 0,625 moles.
What is the molarity of a solution that contains 345 moles KCL in 8.6 L solution?
.487 Kl
What is the molarity of a solution that contains 0.55 moles of a substance dissolved in half a liter of solution?
Molarity means moles per litre. You have to keep that same ratio. i.e. .55moles in 0.5 litres is the same as 1.1 moles in a litre. Therefore the molarity is 1.1 molar.
What is the molarity of a 3.0 liter solution that contains 0.45 moles of solute?
0.15 M
