If the density of a substance is measured as 8.0 g/cm³ with an uncertainty of ±0.2 g/cm³, what is the absolute error in the volume calculated from this density?
0.025 cm³
0.1 cm³
0.2 cm³
0.5 cm³
Volume = mass/density; if mass is constant, the absolute error in volume = (mass * absolute error in density) / (density²).
