The density of your unknown polymer was tested using H 2 O the density of your unknown was tested using ethanol (density 0.789g/) (abbreviated BIOH) instead of water, what would be the results
Testing the density of unknown polymer in water would give you the actual density of the polymer.
Explanation:
The density of ethanol is given in the question as 0.789 g/ml whereas the density of water is 1 g/ml.
Density is defined as the ratio of the mass of the liquid to the volume of the liquid. Water has a reference point as 1 which makes our life easier and the polymer's value does not give us the actual density of the unknown polymer.
Ethanol is formed from water only by evaporation but still, it has a low boiling point as compared to water.
