Answer:
75
Explanation:
is the answer for your question
Since nonmetals have five, six, or seven electrons in their valence shells, it takes less energy to gain the necessary electrons, and therefore form anions.
Answer:
The number of moles of H₂O is 0.135 mol.
The number of moles of LiClO₄ is 0.0449 mol.
Explanation:
Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.
The number of moles of a substance is calculated by:

To find the number of moles of H₂O:
Mass of H₂O in the sample = 2.43g
The molecular weight of H₂O = 18.02g
Number of moles =
= 0.135 mol.
To find the number of moles of LiClO₄:
Mass of LiClO₄ given = 4.78g
The molecular weight of LiClO₄ = 106.39g
Number of moles =
= 0.0449 mol.
