an aluminum sphere has a mass of 25.8 g find the radius of the sphere in centimeters the density of the aluminum is 2.70 g/cm³ and the volume of the sphere is given by the equation V equals 4÷3 times pi times R cubed where are is the radius

An aluminum sphere contains 8.55x 10^22 aluminum atoms. what is the sphere's radius in centimeters? the density of aluminum is 2.70 g/cm3.

One cubic meter (1.00m³) of aluminum has a mass of , and the same volume of iron has a mass of . Find the radius of a solid aluminum sphere that will balance a solid iron sphere of radius 2.00 cm on an equal-arm balance.

What is the average density a single Al-27 atom? Assume that it is a sphere with a radius of 0.143 nm. The masses of proton, electron, and neutron are , , and , respectively. The volume of a sphere is , where r is its radius. Express the answer in grams per cubic
centimeter.

If the density of aluminum is found experimentally to be , what does that suggest about the packing of aluminum atoms in the metal?
