Question

5 of 21 Think and Solve 5.51 Find its density submerged How does this compare with the density of water?

Answer 1

a)

volume, V = 1 L = 10^-3 m^3

Density = mass / volume =10/ 10^-3 = 10^4 kg/m^3

b)

rho / rho w = 10^4 / 10^3 = 10

5.55

density of gold = 19.3 * 10^3 kg/m^3

Volume = mass / density

V = 0.7 / 19.3*10^-3

V = 3.6*10^-5 m^3
