# What number of molecules of water contains #"0.6 atoms"# of #"H"#? What number of molecules is going to contain a total of #"4.5 atoms"#?

Well, apparently you really mean fractional atoms!

Again, this is not physically realistic... atom literally means "indivisible", so you cannot have fractions of an atom.

To find the number of molecules of water containing 0.6 atoms of hydrogen (H), we need to calculate the number of molecules using the molecular formula of water (H2O). Each water molecule contains two hydrogen atoms. Therefore, if 0.6 atoms of hydrogen are present, it would correspond to 0.3 water molecules (since each molecule contains two hydrogen atoms).

To find the number of molecules containing a total of 4.5 atoms, we need to consider the composition of water molecules. A water molecule consists of two hydrogen atoms and one oxygen atom. Therefore, the total number of atoms in one water molecule is 2 (for hydrogen) + 1 (for oxygen) = 3 atoms.

Dividing the total number of atoms (4.5) by the number of atoms per water molecule (3) gives us 1.5 molecules.

So, to answer your questions:

- The number of molecules of water containing 0.6 atoms of hydrogen is 0.3 molecules.
- The number of molecules containing a total of 4.5 atoms is 1.5 molecules.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
