Concept explainers
Interpretation:
The percent amount of carbon dioxide absorbed by the lithium hydroxide canister needs to be deduced under the given conditions.
Concept Introduction:
- 'Yield refers to the amount of product obtained from a reaction.
- 'Theoretical yield' refers to the amount of product obtained from the molar ratio in the balanced equation, whereas the 'actual yield' represents the product recovered from an experimental procedure.
- 'Percent yield' is a ratio of the actual and theoretical yields.
Answer to Problem 44A
% capacity of LiOH canister = 71.7%.
Explanation of Solution
Given:
Mass of LiOH = 155 g
Mass of CO2 absorbed by the LiOH canister = 102 g
Calculations:
The given reaction is:
The balanced equation is:
Step 1:Calculate the moles of LiOH as follows:
Mass of LiOH = 155 g
Molar mass of LiOH = 24 g/mol
Step 2: Calculate the moles of CO2 reacted as follows:
Based on the reaction stoichiometry:
2 moles of LiOH reacts with 1 mole of CO2
Therefore, 6.458 moles of LiOH will combine with:
Step 3: Calculate the theoretical mass of CO2 absorbed as follows:
Moles of CO2 =3.23
Molar mass CO2 = 44 g/mol
Step 4: Calculate the % capacity reached as follows:
Based on equation (1):
Therefore, the LiOH canister has reached 71.7 % of its CO2 absorption capacity.
