Round both of your answers to 2 significant digits.

Consider the combustion of ethylene: c2h4(g)+3o2(g)→2co2(g)+2h2o(g) if the concentration of c2h4 is decreasing at the rate of 3.6×10−2 m/s , what is the rate of change in the concentration of co2? express the rate in molarity per second to two significant digits.
