Question

60 POINTS How many grams of SO2 can be produced if 2.5 moles of O2 are used?

S2 + 2O2 → 2SO2

PLEASE HELP. Use conversion set up and show work.

Answer 1

160 g

Step-by-step explanation:

The balanced chemical equation is:

S2 + 2O2 → 2SO2

From the equation, we can see that for every 2 moles of O2 used, we produce 2 moles of SO2.

Therefore, for 1 mole of O2 used, we produce 1 mole of SO2.

To find the number of grams of SO2 produced, we need to know the molar mass of SO2, which is approximately 64.06 g/mol.

So, to calculate the mass of SO2 produced from 2.5 moles of O2, we can use the following conversion:

2.5 moles O2 x (2 moles SO2/2 moles O2) x (64.06 g SO2/1 mole SO2) = 160.38 g SO2

Therefore, 160.38 grams of SO2 can be produced if 2.5 moles of O2 are used.
