Chemistry Mass Rekationship, Limiting Reactant and Percent Yield
People in confined spaces like those of space vehicles are at risk of carbon dioxide intoxication due to build-up of the gas. In a space shuttle, the carbon dioxide expelled by the crew is removed from the air by a reaction within canisters of lithium hydroxide. The reaction is, LiOH + CO2 → Li2CO3 + H2O
a) How many moles of LiOH can be used to remove the CO2 gas expelled by each crew if on the average, each exhales about 20.0 mol of CO2 daily?
b) If 2355.0 g of LiOH is left in a canister, is this enough to remove all of the CO2 in a space vehicle if the total amount of CO2 expelled by the astronauts through breathing is 2395.0 g? What does this imply?
c) If each contaminant control cartridges contains 750. g of LiOH, how many cartridges must be carried on board the space station assuming that six astronauts can each expel 1.01 kg of CO2 per day? The mission is scheduled to last for 20 days.

Gas Law Stoichiometry 8. Lithium hydroxide, LiOH, is used in spacecraft to recondition the air by absorbing the carbon dioxide exhaled by the astronauts. The reaction that occurs is: 2LiOH(s) + CO2(g) → Li2CO3(s) + H2O(1) How many grams of LiOH (MM 23.95 g/mol) are needed to absorb 625 L of CO2 gas at a pressure of 258 mmHg and a temperature of 27.0°C?

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...
