Cyclopropane, C3H6, is converted to its isomer propylene, CH2=CHCH3, when heated. The rate law is first order in cyclopropane, and its rate constant is (6.70x10^-4)/s at 500°C. if the initial concentration of cyclopropane is (3.860x10^-2) mol/L, what is the concentration after (8.550x10^2) s? Just enter the number  (e.g. 2.48x10^-4) and the unit.  Note: Your answer is assumed to be reduced to the highest power possible. Your Answer:
