Convert 0.935 inches to cm.
Use (4/3)*pi*r^3 to find the volume of the sphere in cubic centimeters.
Use mass = volume x density to find the mass
Then mols = grams/atomic mass.
A pure copper sphere ha a radius of 0.935in. How many moles of copper does it contain? The volume of a sphere is (4/3)3.14r^3, and the density of the copper is 8.96g/cm^3.
(1 in. = 2.54cm)
