How many Zn atoms are in ZnClO3 2?

Answer 1

There are :

1 zinc atom

2 chlorine atoms

6 oxygen atoms

in this zinc chlorate molecule.

Answer 2

First you need to figure out how much zinc is in the compound. The easiest way is to find the percent of Zn in ZnCl and apply it to the mass given. To do this you need the atomic masses and the molecular mass of ZnCl (added atomic masses).

Zn- 65.4

Cl- 35.5

ZnCl- 100.9 grams

65.4 / 100.9 × 100 = 64.8% of ZnCl is Zn

Because we know that in every sample of ZnCl will be composed of 64.8% Zn, we can take 64.8% of 4 moles to find the mass of Zn.

64.8% of 4.00 moles = 2.592 moles Zn in 4 moles ZnCl

Answer 3

The formula unit for a metal, such as zinc, is a single atom. Therefore, the number of atoms in 4.4 moles is 4.4 X Avogadro's Number or 2.65 X 1024 atoms.

Answer 4

There are two Zn atoms in ZnClO3 2. The subscript "2" in the chemical formula indicates that there are two Zn atoms.

Answer 5

There is 1 atom of Zinc.

There are 2 atoms of Chloride.

Answer 6

There are 3 total in one formula unit: 1 of zinc and 2 of chlorine.

Answer 7

The formula weight for Zn is the same as the atomic weight. Therefore, the answer is 4.30 X Avogadro's number.

Answer 8

1 mole of zinc has 6.023 x 1023 atoms

So, 4.1 moles will have 4.1 x 6.023 x 1023 atoms = 24.694 x 1023 atoms

Answer 9

One.

Answer 10

25.690
