Explanation:
- An ionic compound is defined as the compound formed by transfer of electrons from one atom to another.
For example, lithium atom on donating its one valence electron to chlorine atom will result in the formation of an ionic bond and the compound formed is LiCl.
- A molecule is defined as a substance which can contain either same or different elements.
For example, ,
etc are molecules.
- A molecule can contain either a covalent or ionic bond. But an ionic compound will always contain an ionic bond.
The mass percent of oxygen in Nickel()sulfate is
percent.
At first, we look up the atomic masses for the element from the periodic table.
The atomic masses are found to be:
- Ni is
- S is
- O is
Next, we determine how many grams of each element are present in one mole of
of Ni
of S
of O
The mass of one mole is:
So, The mass percent of oxygen
percent.
