Question

You weigh three samples of the same metal, and find their masses to be 41.40 g, 37.22 g, and 43.46 g. the corresponding volumes are 4.5 ml, 4.3 ml, and 4.8 ml. what is the density, d, of the metal?

Answer 1

D=mass/volume
1st sample: D=41.40g/4.5mL
D=9.2 g/mL
2nd sample: D=37.22g/4.3mL
D=8.66 g/mL
3rd sample: D=43.46g/4.8mL
D=9.05 g/mL
Average Density: 9.2+8.66+9.05=26.91
Answer: 26.91/3=8.97 g/mL
