Problem

Five independent measurements of a metal give the following ordered pairs of volume and mass: (10 cm3,  26 g)(10\,\text{cm}^{3},\;26\,\text{g}), (20 cm3,  51 g)(20\,\text{cm}^{3},\;51\,\text{g}), (30 cm3,  120 g)(30\,\text{cm}^{3},\;120\,\text{g}), (40 cm3,  104 g)(40\,\text{cm}^{3},\;104\,\text{g}), and (50 cm3,  129 g)(50\,\text{cm}^{3},\;129\,\text{g}). Which value is most reasonable for the metal’s density? a) 2.9 g/cm32.9\,\text{g}/\text{cm}^3 b) 2.6 g/cm32.6\,\text{g}/\text{cm}^3 c) 4.0 g/cm34.0\,\text{g}/\text{cm}^3 d) 2.5 g/cm32.5\,\text{g}/\text{cm}^3
