<span>Dry cell battery

When an automotive battery is fully charged, the sulfuric acid and water mixture will have a specific gravity of about 1.3. Specific gravity is actually the difference in the weight of water in comparison to a specific fluid. It is measured by a hydrometer. The amount of charge in the battery is normally measured by the specific gravity of the battery. The specific gravity of water is 1 and anything less than one is considered less dense while anything that has a specific gravity of more than 1 is considered more dense than water. </span>

How many liters of carbon dioxide will 0.5 mole of lithium hydroxide (LiOH) absorb? (One mole of any gas occupies 22.4 L under c
Svet_ta [14]

Answer:

0.5 moles of LiOH will absorb 5.6 L of CO_2

Explanation:

According to law of conservation of mass, the sum of mass on the reactant side must be equal to the sum of mass on product side.

The balanced chemical equation is:

2LiOH+CO_2\rightarrow Li_2CO_3+H_2O

2 moles of LiOH absorb 1 mole of CO_2 i.e. 22.4 Liters at STP

0.5 moles of LiOH absorb

=\frac{22.4}{2}\times {0.5}=5.6Liters

0.5 moles of LiOH will absorb 5.6 L of CO_2
