Equal volumes of SO2(g) and O2(g) at STP contain the same number of
incorrect, yet wise reasoning. Helium is lighter than Argon. m/v works once you’re going for volume with 2 balloons with an similar atoms, yet right here you’re coping with diverse ones. you have become tricked with the “volume” note. that is particular as an similar form of atoms, not the quantity of those atoms. because that Argon is heavier, that is going to weigh more suitable, and characteristic more suitable volume. more suitable protons, neutrons, etc., than Helium. artwork from there.
