When 442 mg of NO2 is confined to a 150. mL reaction vessel and heated to 300°C, it decomposes by a second-order process. In the rate law for the decomposition of NO2, k = 0.54 1/(M·s).

A) what is the initial reaction rate?
B) what is the reaction rate if the mass of NO2 increased to 728mg?

I typically always put down my work...but I have no idea where to start with this other than converting NO2 to moles? completely lost here...
