Question

Carbon disulfide burns with oxygen to form carbon dioxide and sulfur dioxide in the following manner:

CS2 + 3 O2 CO2 + 2 SO2

What is the volume of sulfur dioxide (SO2 gas) formed when 2.00 moles of carbon disulfide (CS2) are burned? The reaction is taking place at STP.

5.6 liters
22.4 liters
89.6 liters
44.8 liters

Answer 1

1 mole of CS2 forms 2 moles of SO2,

2 moles of CS2 form 4 moles of SO2,

1 mole of gas at STP is 22.4 liters, so 4 moles of SO2 will be 89.6 liters.

Answer 2

Thank you :)
