You weigh three samples of the same metal, and find their masses to be 39.87 g, 30.84 g, and 38.46 g. the corresponding volumes are 4.3 ml, 3.5 ml, and 4.2 ml. what is the density, d, of the metal?

Density = mass/volume so we get

39.87g/4.3ml = 9.27g/ml
30.84g/3.5ml = 8.81g/ml
38.46g/4.2ml = 9.16g/ml

So adding all mass totals and ml totals and dividing them we get overall density of material

density= mass/volume

Density = 109.17g/11ml = 9.92g/ml density

Hope this helps you! Thank you!!

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.
