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 -------------------------
How many moles are in K2CrO4?

What is formula for potassium chromate?
The chemical formula for potassium chromate is K2CrO4. It consists of two potassium (K) atoms, one chromium (Cr) atom, and four oxygen (O) atoms.
Why K2CrO4 is insoluble in water?
K2CrO4 is insoluble in water because the forces holding the ions together in the solid state are stronger than the forces between the ions and water molecules. The lattice energy of K2CrO4 is high due to the strong ionic bonds between potassium and chromate ions, which makes it energetically unfavorable for the compound to dissociate in water.

What is the dissociation equation for k2CrO4?
The dissociation equation for potassium chromate (K2CrO4) in water is: K2CrO4(s) -> 2K+(aq) + CrO4^2-(aq).
What is the name of this formula k2CrO4?
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
How do you make 0.25N K2CrO4 solution?
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
