Which sample at STP has the same number of molecules as 5 liters of NO2(g) at STP?

(1) 5 grams of H2(g)

(2) 5 liters of CH4(g)

(3) 5 moles of O2(g)

(4) 5 × 1023 molecules of CO2(g)

(2) is the only correct answer. (1) 5 grams of H2 is 2.5 mols of this gas, which would result at STP 22.4 2.5 Liters (according to Avogadro's law). 5 moles of O2 would result in 5 22.4 Liters, and (4) 5 10^23 molecules of CO2 (which is what I assume you meant) would be 5 mols, which would result in 5 22.4 Liters.

(2) is your answer
