At 25∘C, the decomposition of dinitrogen pentoxide, N2O5(g), into NO2(g) and O2(g) follows first-order kinetics with k=3.4×10−5
s−1. A sample of N2O5 with an initial pressure of 760 torr decomposes at 25∘C until its partial pressure is 650 torr. How much time (in seconds) has elapsed?

it decreases the density of the object the air bubbles take up space. it increases the volume of the object slightly but the objects weight remains the same, hence the objects density decreases
