<h2>Answer:</h2>

Numer of moles of Li₂CO₃:

\longrightarrow\: n_{(Li_2 CO_3)} = \dfrac{38.5}{(6 \times 2) + 12 + (16 \times 3)}

\longrightarrow\: n_{(Li_2 CO_3)} = \dfrac{38.5}{12+ 12 +48}

\longrightarrow\: n_{(Li_2 CO_3)} = \dfrac{38.5}{72}

\longrightarrow\: n_{(Li_2 CO_3)} = 0.53473 \: mol

Chemical Reaction:

2 LiOH(s) + CO₂(g) → Li₂CO₃(s) + H₂O(l)

  • 1 mole of Li₂CO₃ is formed from 2 moles of LiOH.

Therefore, applying unitary method:

  • 0.53473 mole of Li₂CO₃ is formed from 2 × 0.53473 = 1.06946 moles of LiOH.

How many stereoisomers are possible for 1 2-dichlorocyclopentane?
slega [8]
<span>There are only three stereoisomers of 1,2-dimethylcyclopentane. As there are only two chiral carbons, so the maximum number of stereoisomers is 4, but two are the same meso-compound which means that there are only 3.</span>
