a single 3.0mm porous bead can have a surface area of 1.0*10^6 cm^2. If a
car has two catalytic converters, each with 5.0*10^3 beads, calculate
the surface area of the two catalytic converters in km^2.
Calculate number of total beads in both
converters : 5000 beads x 2 = 10000 beads total
One bead has 1.0 x 10^6 cm^2,
total surface area is 1.0 x 10^6 cm^2 x 10000 beads = 1.0 x 10^10 cm^2
You are asked to give an answer in km^2.
x 10^10 cm^2 x 1.0e^-10 km^2 / 1 cm^2 = 1 km^2
Final answer is 1 km^2
