Question

Liquid carbon disulfide (CS2) reacts with 44.8 L O2 gas to produce the gases carbon dioxide (CO2) and sulfur dioxide (SO2). What is the mass of carbon dioxide produced?

Answer 1

What is the mass of carbon dioxide produced?

29.3 g

What is the mass of sulfur dioxide produced?

85.4 g

When making the calculations, did you need to find the number of moles?

Yes

Answer 2

The balanced chemical reaction is:

CS2 + 3O2 = CO2 + 2SO2

First, we assume that the gases here are ideal and that the reaction is done at STP so that 22.4 L of the gas is equal to 1 mol. We use the reaction and the relation of the substances to calculate what is asked. 

44.8 L (1 mol / 22.4 L) (1 mol CO2 / 2 mol SO2) (44.01 g / mol) = 44.01 g CO2
