The gas phase decomposition of dinitrogen pentoxide at 335 K N2O5(g)2 NO2(g) + ½ O2(g)

is first order in N2O5 with a rate constant of 0.00470 s-1.

If the initial concentration of N2O5 is 0.177 M, the concentration of N2O5 will be 0.0384 M after
s have passed. (I need specific instructions on how to solve this problem with a simple scientific calculator please!!)
