Daniel has a sample of pure copper. its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). what’s the density of the sample?

0.11 g/cm3

8.96 g/cm3

11.1 g/cm3

896 g/cm3

Explanation:

the parameters given

mass of pure copper, m = 89.6g

volume of copper, v =

we are to find density, ρ = mass/volume

        89.6 g/

ρ = 8.96 g/

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
