I am not completely sure what your question is, but I think you are asking about the molar mass? It is a mole conversion. For example, if you start with atoms and want grams, you would need to get rid of the atoms unit first then get rid of the mols unit: so you would have to multiply it by (1 mol / Avogadro's number) X (molar mass / 1 mol) = this is the conversion factor that gives you grams. I hope this helped!
Have a fantastical day,

Answer:
In an acidic solution i.e pH is lower than 7 has higher concentration of hydronium ions compare to the hydroxide ions.
Explanation:
Acidic solutions are those solutions which have pH value less than 7.
Alkaline solutions are those solution which has pH more than 7.
Neutral solutions are those solution which has pH value equal to 7.
The pH of the solution is defined as negative logarithm of hydronium ion concentration present in an aqueous solution .
- Higher pH value indicates that hydronium ions present in the solution are less than the hydroxide ions.
- Lower pH value indicates that hydronium ions present in the solution are more than the hydroxide ions.
So, in an acidic solution i.e pH is lower than 7 has higher concentration of hydronium ions compare to the hydroxide ions.

Answer:
true
Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral
