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:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
