It is definitely not an element. As far as the other three, I'm honestly not sure, but I'm going to make an educated guess that it is either a solution or a heterogeneous mixture. Since you cannot see separate phases in leather, I would deduce that it is not heterogeneous. My best guess would be for solution.
I know it's not much of a help, but that's all I've got.
Just know that you tryed in thatz all that matter!
To determine the mole fraction of a substance in a mixture, you divide the moles of the substance by the total moles of all substances in the mixture. This gives you a ratio that represents the proportion of that substance in the mixture.
The amount of each substance in a mixture can change if more of a substance is added or removed, causing the proportions of the substances in the mixture to change. However, the total amount of each substance in the mixture will remain constant.
A solution is a mixture in which a substance dissolves into another substance at the molecular level. The substance that dissolves is called the solute, while the substance it dissolves into is called the solvent. The result is a homogenous mixture with uniform composition throughout.
