Which of the following best explains why measuring density allows a student to identify an unknown substance even when the size and shape of the sample are unknown?
(a) Density remains constant only for samples with regular, uniform shapes; irregularly shaped pieces have different densities.
(b) Density depends on sample size because larger masses increase faster than volumes, so bigger pieces have greater densities.
(c) Density is an intrinsic property determined by the material’s internal structure, so its value is independent of sample size or shape.
(d) Dividing a sample’s mass by its volume cancels all measurement errors, so density is always calculated perfectly.
