Gas Stoichiometry involves chemical reactions that contain gases.
Concept #1: Gas Stoichiometry
Concept #2: Gas Stoichiometric Chart
Example #1: What mass of Ag2O is produced when 384 mL of oxygen gas at 736 mmHg and 25 ºC is reacted with excess solid silver?
Practice: The metabolic breakdown of glucose (C6H12O6) (MW: 180.156 g/mol) is given by the following equation:
C6H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l)
Calculate the volume (in mL) of CO2 produced at 34°C and 1728.9 torr when 231.88 g glucose is used up in the reaction.
Practice: The oxidation of phosphorus can be represented by the following equation:
P4 (s) + 5 O2 (g) → 2 P2O5 (g)
If 1.85 L of diphosphorus pentoxide form at a temperature of 50.0 ºC and 1.12 atm, what is the mass (in g) of phosphorus that reacted?
Practice: Determine the mass (in grams) of water formed when 15.3 L NH3 (at 298 K and 1.50 atm) is reacted with 21.7 L of O2 (at 323 K and 1.1 atm).
4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (g)
