In Chem, do we have to know abt Avogadro's constant.(6.0 x 10^23)????

Chemistry November 2009 qp12 qs 12. Why is it 0? The ratio being 2:1 the answer should be b? Anyone?

Since reaction takes place at room temp then reacting mole ratio is equal to reacting volume ratio so all the gas gets used up and true is nothing remaining.Hence A is the ans

How is the ratio equal? When it says 2dm3 reacts with 1dm3 ? It should be 2:1 then no?

yeah nd whole 2:1 forms a liquid.....so no gas left
