From mole ratios, the mass ratio of different elements can be predicted. Also the volume can be predicted based on density for liquids and ideal gas law equation for gases. From the mole ratios, the empirical formula can be predicted, as well as the molecular formula given another data which is mass of the sample.
The answer is homogeneous
Explanation:
The states may differ depending on the reactions
The answer to this is t<span>he atom is mostly empty space.</span>
