Answer:

Mass of Li2O = 2.93g

Molecular mass of Li2O = 29.88g/mol

No of mole of Li2O = Mass/Molar mass

No of mole of Li2O = 2.93/29.88

No of mole of Li2O = 0.0981mol

Answer:

0.1 mol

Explanation:

Number of mole= mass/molar mass

lithium have a mass number of 7 and oxygen have a mass number of 16.

= 30

therefore, number of moles = 2.93/30

= 0.10

Based on the observations from, the substance that water is more attracted to are polar substances.

<h3>What is the Polarity of water?</h3>

Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.

Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.

Since water molecules are polar, they are more attracted to molecules that are also polar.

Thus, based on the observations from, the substance that water is more attracted to are polar substances.
