how much oxygen is required to convert total so2 into so3 tell me the percentage ratio of so2:o2

the reaction is so2+1/2o2=so3

each O2 reacts with 2SO2, so in moles, the ratio would be 2:1

in mass, convert from moles to grams.

To determine the percentage ratio of SO2 to O2 in the reaction SO2 + 1/2 O2 → SO3, we need to consider the stoichiometry of the reaction.

The balanced equation shows that for every 1 mole of SO2 consumed, 1/2 mole of O2 is required to produce 1 mole of SO3.

Therefore, the ratio of SO2 to O2 in terms of moles is 1:1/2 or 2:1.

To convert this ratio to a percentage ratio, you need to find the sum of the parts, which in this case is 2 + 1/2 = 2.5.

To determine the percentage ratio, you can divide each part of the ratio by the sum and multiply by 100.

SO2: (2/2.5) x 100 = 80%

O2: (1/2.5) x 100 = 40%

Therefore, the percentage ratio of SO2 to O2 in the reaction is approximately 80% : 40%.
