How many atoms are in 25.8 grams of Hg (mercury)

Chemistry

Answer:

7.74568E22 or 7.74568 * 10^22 atoms

Explanation:

To find this, we first must find the moles of mercury in 25.8 grams. Since the molar mass of Hg is 200.59, we can find moles of Hg from 25.8 / 200.59 = 0.1286

To find the amount of atoms, we must multipy the amount of moles by Avagadro's number.

.1286 * 6.02214076 * 10²³ is 7.74568E22 or 7.74568 * 10^22 atoms

The image below shows two nitrogen atoms. For these two atoms to form a stable molecule, N2, how many electrons would have to be
maxonik [38]
There are six electrons in the covalent bonds.

Two N atoms would be :N:· + ·:N:
An N₂ molecule would be :N:::N: or :N≡N:
This gives each N atom an octet of eight electrons in its valence shell.

What is the expected ionic charge when group VI elements participate in ionic bonds?
valina [46]
Group 6 elements usually have extra electrons to make give them an octet. So, they have 6 electrons to start and when they have an octet, they have 8.

We can find the charge by doing simple math 6 - 8 = -2
