How many moles of oxgen are in one mole of calcium carbonate?
1 mol CaCO3 x (3 mols O atoms/1 mol CaCO3) = 3 mols O atoms.
plz explain in detail
What is it you don't understand? Look at the formula for CaCO3. For every 1 mole of CaCO3 you start with you have 1 mol Ca atoms, 1 mol C atoms and
3 mols O atoms.
To determine the number of moles of oxygen in one mole of calcium carbonate, you need to know the chemical formula of calcium carbonate and its molar mass.
The chemical formula of calcium carbonate is CaCO3, which signifies that each molecule of calcium carbonate contains one calcium atom (Ca), one carbon atom (C), and three oxygen atoms (O).
To calculate the molar mass of calcium carbonate, you can find the atomic masses of the individual elements from the periodic table and calculate their sum. The atomic masses are approximately:
- Calcium (Ca): 40.08 g/mol
- Carbon (C): 12.01 g/mol
- Oxygen (O): 16.00 g/mol
Molar mass of CaCO3 = (1 x Ca) + (1 x C) + (3 x O)
= (1 x 40.08 g/mol) + (1 x 12.01 g/mol) + (3 x 16.00 g/mol)
= 40.08 g/mol + 12.01 g/mol + 48.00 g/mol
= 100.09 g/mol
Now, since the molar mass of calcium carbonate is 100.09 g/mol, this means that in one mole of calcium carbonate, there are 100.09 grams.
To calculate the number of moles of oxygen in one mole of calcium carbonate, you need to look at the ratio of oxygen atoms to calcium carbonate molecules. As stated earlier, each calcium carbonate molecule contains 3 oxygen atoms.
Therefore, in one mole of calcium carbonate, there are 3 moles of oxygen atoms.
In conclusion, there are 3 moles of oxygen in one mole of calcium carbonate.
