help pls!

2SO3(g)2SO2(g)+O2(g) Suppose o vessel contains SO3 at a concentration or 0.680M. Calculate the concentration of SO3 in the vessel 0.630 seconds later, You may assume no other reaction is important. Round your answer to 2 significant digits At a certain temperature this reaction follows first-order kinetics with a rate constant of 3.5051 : 2SO3(g)2SO2(g)+O2(g) Suppose a vessel contains SO3 at a concentration of 0.680M.
