Answer to Question #87953 in General Chemistry for Ifechidere Okoroafor

Question

Your car’s catalytic converter loses 50 ng Pd for each km you drive. How many miles do you drive before you lose 1 g?

Answer 1

m(Pd) = 50 ng = 50×10^-9 g = 5×10^-8 g.

5×10^-8 g – 1 km

1 g          – X km

X = 1/5×10^-8 km = 2×10⁷ km.

1 mile   – 1.609 km

Y miles – 2×10⁷ km

Y = 2×10⁷/1.609 miles = 1.243×10⁷ miles.
