By dividing the percentage composition with the molar mass of that element we will get the empirical formula. Then using that empirical formula and formula mass we can find the molecular formula.
<u>Explanation:</u>
The chemical properties of any substance are defined obviously by the different types and relative amounts of atoms constituting its primary entities (in case of covalent compounds the primary entities are molecules and ions in the event of ionic compounds).
A percent composition of any compound gives the mass percent of each element present in the compound; in addition to that frequently it is determined experimentally and utilized to derive an empirical formula of any compound. An empirical formula mass of any covalent compound could be comparable with the molar or molecular mass of a compound to acquire a molecular formula.
Answer:
The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023). Calculate the number of atoms in 2.45 mol of copper. A silver ring contains 1.1 x 1022 silver atoms.

Answer: The hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
1. Solution with pH of 6
![6=-\log [H^+]](https://tex.z-dn.net/?f=6%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-6}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-6%7D)
2. Solution with pH of 4
![4=-\log [H^+]](https://tex.z-dn.net/?f=4%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-4}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-4%7D)
Thus the hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
