Answer:
There are approximately 5.55 moles
Explanation:
Calcium carbonate will be formed which is insoluble in water.
The answer is a) K and CrO4 only.
Moles of P = 56,4g/30,974g/mole = 1,82 moles P
moles of O = 43,6/15,999 = 2,73 moles of O
converting to the simplest ratio:
For P : 1,82/1,82 = 1
For O : 2,73/1,82 = 1,5
1 P and 2 oxygens.
PO2 -> the empirical formula
