how many molecules of N2 could fit in a 2.00L soda bottle at 23C and 755mmHg

Answer 1

Set up: convert units --> PV=nRT --> PV/RT=n --> moles to molecules.

(0.993atm*2.00L)/(0.08206*296.15K)=0.08176 mol N2

0.08176 mol*(6.022x10^23 molecules/1 mol)=4.92x10^22 molecules N2

Let me know if this helps!
