20) assuming that 1 mole (6.02*10^(23) molecules) of an idealgas has a volume of 22.4 L at standard temperature and pressure(STP) and that nitrogen, which makes up roughly 80% of the air webreathe, is an ideal gas, how many nitrogen molecules are there inan average 0.5L breath at STP?? 22)A tank is in the shape of an inverted cone, having height h =2.5 m and base radius r = 0.75 m. If water is poured into the tankat a rate of 15 L/s, how long will it take to fill the tank?
thank you
