Explanation:

The question is incomplete; as the mixtures are not given.

However, I'll give a general explanation on how to go about it and I'll also give an example.

The percentage of a component in a mixture is calculated as:

Where

E = Amount of element/component

T = Amount of all elements/components

Take for instance:

In

The amount of all elements is: (i.e formula mass of )

The amount of calcium is: (i.e formula mass of calcium)

So, the percentage component of calcium is:

The amount of hydrogen is:

So, the percentage component of hydrogen is:

Similarly, for oxygen:

The amount of oxygen is:

So, the percentage component of oxygen is:
