The table below shows some physical properties of two unknown samples. Physical Properties Sample Mass Solubility (in water) C 200 g 36 g/mL D 500 g 180 g/mL What would best support whether the two samples are of the same substance or not? The two substances are the same because the property that depends on the amount of the sample is different. The two substances are the same because the property that is independent of the amount of the sample is different. The two substances are not the same because the property that is independent of the amount of the sample is different. The two substances are not the same because the property that depends on the amount of the sample is different.
