Step-by-step explanation:
15) The both diamonds- the diamond used as a grinding tool and the two -carat diamond both have the same density because density is an intensive or intrinsic property of a substance. It does not depend on the mass of the substance present.
16) Area of magnesium = Length * width = 0.104 * 10^2 cm * 2.52 * 10^-1 cm = 2.62 cm^2
Density = mass/area * thickness
Density * area * thickness = mass
thickness = mass/Density * area
thickness = 0.104 g/ 1.74g/cm3 * 2.62 cm^2
thickness = 0.0228 cm
