    3)You use 10×0.30 = 3 moles of Tl^+ for every 20×0.10 = 2 moles of VO3^-. Every Tl^+ ion loses 2 electrons, so for every equivalent of Tl^+, you get 2(3) = 6 electrons to be taken up by the V atoms. In VO3^-, V is present as +5. 6 electrons are taken up by 2 equivalents, so 1 equivalent will...

    1) Umm, you just read the topic "The kinetic theory of gases"(on page 99 of coursebook written by Roger Norris). Do you observe that all points are related to GASES while HCl IS A LIQUID. So it can be clearly said that IT IS THE ONE WHICH MOST DEVIATE FROM IDEAL GAS BEHAVIOUR. You got na?
