Answer:
Let us first write the balanced chemical equation for this reaction.
S + O2→ SO2
As per stoichiometry 1 mole of oxygen will produce 1 mole of sulphue dioxide. So 2.5 mole of oxygen will produce 2.5 mole of sulphur dioxide.
We know,
1 mole of any substance=Gram molecular mass of that substance.
So, 1 mole of SO2=Gram molecular mass of SO2
=(1×32)+(2×16) g
=64 g
So mass of 2.5 moles of SO2 = 64×2.5=160 g of SO2
Hence the answer is 160 g of SO2.
Hope you understood the answer.
Thank you.
