A compound's empirical formula is N2O5. If the formula mass is 108 amu, what is the molecular formula?

i just learnt this recently but i need to look through my notes again

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

answer carbon and three oxygen atoms;
