To determine the number of atoms in Zinc Chloride (ZnCl2), we need to break down the molecular formula and calculate.
ZnCl2 consists of one zinc atom (Zn) and two chlorine atoms (Cl). The subscript '2' indicates that there are two chlorine atoms.
Let's calculate the total number of atoms in ZnCl2:
1 Zinc atom (Zn)
2 Chlorine atoms (Cl)
Therefore, there are three atoms in Zinc Chloride, ZnCl2.
To determine the number of atoms in a compound, you need to know the formula and the number of each type of atom present.
The formula for zinc chloride, ZnCl2, indicates that there is one zinc atom (Zn) and two chlorine atoms (Cl) in each molecule.
To find the number of atoms, you need to multiply the number of molecules by the number of atoms in each molecule.
Step 1: Calculate the number of molecules:
To find the number of molecules, you need to know the quantity of zinc chloride. Let's assume we have 1 mole of zinc chloride.
Step 2: Calculate the Avogadro's number:
1 mole of any substance contains 6.022 x 10^23 entities, known as Avogadro's number.
Step 3: Multiply the number of molecules by Avogadro's number:
1 mole of zinc chloride = 6.022 x 10^23 molecules of ZnCl2
Step 4: Multiply the number of molecules by the number of atoms in each molecule:
Since there is 1 zinc atom and 2 chlorine atoms in each molecule of ZnCl2, you would multiply the number of molecules by the sum of these quantities (1 + 2).
Total number of atoms = (Number of molecules of ZnCl2) x (Number of atoms in ZnCl2)
= (6.022 x 10^23 molecules) x (1 + 2 atoms/molecule)
= 6.022 x 10^23 molecules x 3 atoms/molecule
The total number of atoms of zinc and chlorine in 1 mole of zinc chloride (ZnCl2) is 1.8066 x 10^24 atoms.
