Stoichiometry of Reactions Involving Gases
use molar volumes as conversion factors.
- at STP: molar volume of any gas is 22.414 L/mol.
- if not at STP: molar volume of any gas is RT/P.
What volume of SO2(g) is produced at STP by the combustion
of 1 metric ton of coal containing 10 g of sulfur, S8(s)?
Potassium superoxide (KO2) is used to purify air in spacecraft.
What weight of KO2 is required to recycle 1.0 L of CO2 at 25oC
4 KO2(s) + 2 CO2(g) = 2 K2CO3(s) + 3 O2(g)
