Answer:
320.3 grams of SO2 can be produced
Step-by-step explanation:
In order to calculate the amount of SO2 produced, we first need to write a balanced chemical equation for the reaction between O2 and sulfur:
2 SO2 + O2 -> 2 SO3
From the equation, we can see that 1 molecule of O2 reacts with 2 molecules of SO2 to produce 2 molecules of SO3.
Therefore, we need to convert the number of O2 molecules to the number of SO2 molecules in order to calculate the amount of SO2 produced.
1 molecule of O2 reacts with 2 molecules of SO2, so:
2.5 molecules of O2 * (2 molecules of SO2 / 1 molecule of O2) = 5 molecules of SO2
Now that we have the number of SO2 molecules produced, we can calculate the mass of SO2 using its molar mass. The molar mass of SO2 is approximately 64.06 g/mol.
5 molecules of SO2 * (64.06 g/mol) = 320.3 grams of SO2
Therefore, if 2.5 molecules of O2 react with sulfur to form SO2, then 320.3 grams of SO2 can be produced.
