Which o^ these possesses more mass, a sphere of Mecury (Hg) with a diameter of 2.00 cm or a cube of lead (Pb) measuring 2.00 cm on each side?  Volume of a sphere = 4/3(pie)r^3.

Steve · Answer

pi NOT pie!!! You need to look up the densities of Hg and Pb, then multiply each volume by its density to find the two masses. Then just compare them.
