1.	1 lit of oxygen and 3 lit of SO_(2) at STP are reacted to produce sulphur trioxide . Then the ratio of between volume of sulphur trioxide and that of sulphur dioxide after reaction and weight of SO_3 formed (in grams) respectively are
Answer» `1:2 , 7:14 gms` `2:1 , 14.28 gms` `2:1 , 7.14 gms` `1:1 , 14.28 gms` Solution :`2SO_(2)+O_(2)rarr2SO_(3)` 2 lit `LARR` 1 lit `larr` 2 lit IMPLIES 1 lit `SO_(2)` left `therefore (SO_(3))/(SO_(2))=(2)/(1)` WEIGHT of `SO_(3)=(2)/(22.4)xx80=7.14g`
