The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
I honestly don’t know sorry
Answer:
the answer would be (A.) and (D.).
Explanation:
the reason for that being is because if calcium sulfate is a main component of plaster of paris you would need to find out what is in it that makes it the main component aka (the formula) therefore part of the answer is (A.). The other part of the answer was (D.) because you would need to find the amount of calcium sulfate that contain 12 grams of oxegeon atoms because you finding the answer to that could lead to the answer of what is the main component of plaster of Paris.
526 L O2 x 1 mol O2 / 22.4 L = 23.5 mol O2
