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 -------------------------
Formula: K2CrO4
It depends on how much you have.
K2CrO4
Reaction of Potassium hydroxide or any potassium salt of a weak acid with chromic acid produces Potassium chromate. KOH + H2CrO4 ----> K2CrO4 + H2O K+ + H2CrO4 ----> K2CrO4 + H+

KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
