Lead is an elementary substance that occurs as a malleable metal
with a density of 11.4 g/mL at ambient temperature and
pressure.
Lead metal can be extracted from a mineral called galena, which
contains 86.6%% lead by mass. A particular ore contains
68.5%% galena by mass.
If the lead can be extracted with 92.5%% efficiency, what
mass of ore is required to make a lead sphere with a
3.00 cmcm radius?
Express your answer with the appropriate units.
