Question

How many oxygen (O) atoms are in each of the following molecules?

1. Ca(OH)2
2. Fe(ClO3)2
3. Zn3(PO4)2
4. Mg(CH3COO)2

Answer 1

There are different numbers of oxygen atoms in each of the given molecules: calcium hydroxide has 2, iron(II) chlorate has 6, zinc phosphate has 8, and magnesium acetate has 4 oxygen atoms.

Step-by-step explanation:

In each of the given molecules:

1. Ca(OH)2: There are 2 oxygen (O) atoms in each molecule of calcium hydroxide.

2. Fe(ClO3)2: There are 6 oxygen (O) atoms in each molecule of iron(II) chlorate.

3. Zn3(PO4)2: There are 8 oxygen (O) atoms in each molecule of zinc phosphate.

4. Mg(CH3COO)2: There are 4 oxygen (O) atoms in each molecule of magnesium acetate.

To determine how many oxygen atoms are in each molecule, we analyze the formulas given:

For Ca(OH)2, there are 2 hydroxide groups (OH), each containing one oxygen atom, for a total of 2 oxygen atoms.

For Fe(ClO3)2, there are 2 chlorate groups (ClO3), each containing 3 oxygen atoms, resulting in 6 oxygen atoms.

Zn3(PO4)2 has 2 phosphate groups (PO4), with each group having 4 oxygen atoms, so it has 8 oxygen atoms.

Lastly, Mg(CH3COO)2 has 2 acetate groups (CH3COO), with each group containing 2 oxygen atoms, adding up to 4 oxygen atoms.
