Question
3.The average density of the material in intergalactic space is approximately 2.5 ´ 10–27 kg/m3. What is the volume of a gold sample, = 19 300 kg/m3, that has the same mass as 8.0 ´ 1024 m3 of intergalactic space? 3.The average density of the material in intergalactic space is approximately 2.5 ´ 10–27 kg/m3.

What is the volume of a gold sample, = 19 300 kg/m3, that has the same mass as 8.0 ´ 1024 m3 of intergalactic space?Explanation / Answer
m = v*rho
m = 2.5 x 10^-27 * 8 x 10^24 = 0.02 kg
now volume = m/rho
v = 0.02/19300 = 1.036 x 10^-6 m^3
