Seven. According to the formula you've posted:
- one Calcium atom
- two Chromium atoms
- four Oxygen atoms
At a loose guess, it's a variety of Chromite, with the iron atom replaced by calcium.

∙ 13y agoim sorry but this is most stupidest question i ever seen how many oxygen are in Kr2CrO7 try looking at number at the end of letter O
Wiki User

It depends on how much you have.
Chemical formula for potassium and chromate?
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+
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 -------------------------
