How many moles of oxygen atoms are contained in the following?

A) 3.31 mil KMnO4
B)43.4 mol CO2
C)2.45e-2 mol CuSO4•5 H2O

For A: The moles of oxygen atoms are 13.24 moles

For B: The moles of oxygen atoms are 86.8 moles

For C: The moles of oxygen atoms are 0.2205 moles

Explanation:

1 mole of contains 1 mole of potassium atoms, 1 mole of manganese atoms and 4 moles of oxygen atoms

So, moles of oxygen atoms = (3.31 × 4) = 13.24 moles

1 mole of contains 1 mole of carbon atoms and 2 moles of oxygen atoms

So, moles of oxygen atoms = (43.4 × 2) = 86.8 moles

1 mole of contains 1 mole of copper atoms, 1 mole of sulfur atoms, 10 moles of hydrogen atoms and 9 moles of oxygen atoms

So, moles of oxygen atoms =

it is called acid bonding
