The density of lead is 11.3 g/cm3 .What is this value in kilograms per cubic meter?

A solid piece of lead has a mass of 23.94 g and a volume of 2.10 cm 3. From these data, calculate the density of lead in SI units (kilograms per cubic meter).

The quantity called mass density is the mass per unit volume of a substance. What are the mass densities in SI units of the following objects? How many significant figures should each calculation have?(a) A 215 cm3 solid with a mass of 0.0179 kg.(b) 95 cm3 of a liquid with a mass of 77 g.

The surface area of a ball is measured to be A = 95 cm2.(a) Write an equation for the radius of the ball, r, treating it as a sphere, in terms of its surface area. (b) The mass is measured to be M = 45 g. Calculate its density ρ in g/cm3. (c) What is the density Pkg/m3 in kg m3?

(a) What is the average density of the sun? (b) What is the average density of a neutron star that has the same mass as the sun but a radius of only 20.0 km?
