First, write out your balanced equation. CS2 (l) + 3O2 (g) → CO2 (g) + 2SO2 (g) Then, since you know by Avogadro's Law, the volume is directly proportional to the number of moles. Since 3 moles of oxygen gas form one mole of carbon dioxide, you divide 4.50 x 102 mL, or 450. mL, and you get 150. mL of CO2 (g). Since 3 moles of oxygen produce 2 moles of sulfur dioxide, you take 450. mL and multiply it by (3/2) and get 300. mL of SO2 (g).
11L and 22mL
1 mole of gas occupies 22.4 liters at STP. Therefore 3.5/22.4 = 0.15625 moles of SO2. There are thus 0.15625 moles of O2 needed to react with solid sulfur because S + O2 ---->SO2. 0.15625 moles of oxygen occupies 0.15625 x 22.4 liters = 3.5 liters O2 required.
The Earth's atmosphere is approximately 79% Nitrogen, 20% Oxygen and 1% other gasses - including Argon, Neon and Carbon Dioxide.

The ration of the carbon dioxide produced to the volume of oxygen consumed
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere

Volume of oxygen consumed, Volume of carbon dioxide produced. From this you can calculate the respiratory quotient/rate of respiration.
It contains the volume of oxygen needed to supply the victim with rescue breaths of 100% oxygen.
it is left so that there is sufficient time for enough oxygen to be absorbed and for the carbon dioxide to be released
