Consider calcium phosphate.

1) How many moles of calcium atoms are present in one mole of calcium phosphate?
2) How many moles of phosphorus atoms are present in one mole of calcium phosphate?
3) How many moles of oxygen atoms are present in one mole of calcium phosphate?

the molecule is Ca3(PO4)2, which is Ca3P2O8

That tells you how many atoms in each molecule, so it is the same as the ratio of moles

Ca3(PO4)2.

Look at the formula above. You can see for 1 mol Ca3(PO4)2 you have 3 mols Ca, 2 mols P and 8 mols O and 2 mols of PO4^3-.

To answer these questions, we need to determine the chemical formula for calcium phosphate. Calcium phosphate has the chemical formula Ca3(PO4)2.

1) In one mole of calcium phosphate, there are three moles of calcium atoms. This is because the subscript "3" in Ca3(PO4)2 indicates that there are three calcium atoms present in each molecule of calcium phosphate.

2) In one mole of calcium phosphate, there are two moles of phosphorus atoms. This is because the subscript "2" in Ca3(PO4)2 indicates that there are two phosphorus atoms present in each molecule of calcium phosphate.

3) In one mole of calcium phosphate, there are eight moles of oxygen atoms. This is calculated by adding up the total number of oxygen atoms from all the components of calcium phosphate. The phosphate ion (PO4) has four oxygen atoms, and since there are two phosphate ions in Ca3(PO4)2, there are a total of (4 x 2) = 8 oxygen atoms present in each molecule of calcium phosphate.

To answer these questions, we need to know the chemical formula of calcium phosphate.

The chemical formula of calcium phosphate is Ca3(PO4)2. From this formula, we can determine the number of moles of each element present in one mole of calcium phosphate.

1) To find the number of moles of calcium atoms, we look at the subscript of calcium in the formula. In this case, the subscript is 3, which means there are 3 calcium atoms in each molecule of calcium phosphate. Therefore, in one mole of calcium phosphate, there would be 3 moles of calcium atoms.

2) To find the number of moles of phosphorus atoms, we look at the subscript of phosphorus in the formula. In this case, the subscript is 2, which means there are 2 phosphorus atoms in each molecule of calcium phosphate. Therefore, in one mole of calcium phosphate, there would be 2 moles of phosphorus atoms.

3) To find the number of moles of oxygen atoms, we need to consider the total number of oxygen atoms in the formula. There are 4 oxygen atoms in each phosphate ion (PO4)-2, and since there are 2 phosphate ions in each molecule of calcium phosphate, there would be a total of 4 x 2 = 8 oxygen atoms in one molecule. Therefore, in one mole of calcium phosphate, there would be 8 moles of oxygen atoms.
