Step-by-step 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:

`\%C_E = (E)/(T) * 100\%`

Where

E = Amount of element/component

T = Amount of all elements/components

Take for instance:

In
`(Ca(OH)_2)`

The amount of all elements is: (i.e formula mass of
`(Ca(OH)_2)`)

`T = 1 * Ca + 2 * H + 2 * O`

`T = 1 * 40 + 2 * 1 + 2 * 16`

`T = 74`

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

`E = 1 * Ca`

`E = 1 * 40`

`E = 40`

So, the percentage component of calcium is:

`\%C_E = (E)/(T) * 100\%`

`\%C_E = (40)/(74) * 100\%`

`\%C_E = (4000)/(74)\%`

`\%C_E = 54.05\%`

The amount of hydrogen is:

`E = 2 * H`

`E = 2 * 1`

`E = 2`

So, the percentage component of hydrogen is:

`\%C_E = (E)/(T) * 100\%`

`\%C_E = (2)/(74) * 100\%`

`\%C_E = (200)/(74)\%`

`\%C_E = 2.70\%`

Similarly, for oxygen:

The amount of oxygen is:

`E = 2 * O`

`E = 2 * 16`

`E = 32`

So, the percentage component of oxygen is:

`\%C_E = (E)/(T) * 100\%`

`\%C_E = (32)/(74) * 100\%`

`\%C_E = (3200)/(74)\%`

`\%C_E = 43.24\%`
