Question

1 L of oxygen and 3 L of SO2 at STP are charged to produce sulphur trioxide the ratio between volume of sulphur trioxide and sulphur dioxide after reaction and weight of a sore three formed in grams respectively are

Answer 1

Answer:

We can also say that one litres of oxygen reacts with two litres of sulphur trioxide. We are given that one litres of oxygen and three litres of sulphur dioxide reacts to form sulphur trioxide. So we can say that three litres of sulphur trioxide is formed. So, the ratio of volumes is $1:1$.
