From the stoichiometry of the reaction, 1.4 * 10^-3 g is produced.
<h3>What mass of water is produced?</h3>
The equation of the reaction is written as; CO2 + 2LiOH → Li2CO3 + H2O. This can help us to apply the principle of stoichiometry here.
Thus;
Number of moles of CO2 = 0.00345 g/44 g/mol = 7.8 * 10^-5 moles
If 1 mole of CO2 produced 1 mole of water
7.8 * 10^-5 moles of CO2 produced 7.8 * 10^-5 moles of water
Mass of water produced = 7.8 * 10^-5 moles * 18 g/mol = 1.4 * 10^-3 g

There can be three mole ratios that can be written involving three substances.It depends on the constant of your reactant to your product. It also depends on the asked mole ratio. But the maximum would be 3 mole ratios because you have 3 substances in your reaction.
I think its an Ionic bond although i am not sure about
Given that in the alien planet the names of substances and the units in which they are measured in not familiar.
8 quibs of a substance called skvarnik is present.
The conversion factor between sleps and quibs is: 9 sleps = 13 quibs
Converting 8 quibs of skvarnick to sleps:

5.54 when rounded to nearest tenth becomes 5.5.
So the correct answer would be 5.5
