Question

Calculate the number of moles of atom of Nitrogen in 6.022 × 10²³ number of N2 molecular​

Answer 1

Answer:

2 × Na

Explanation:

You known that one molecule of Nitrogen

gas, N², contains two atoms of nitrogen, 2 × N.

Now, a mole is simply a very, very large collection of

particles. In order to have one mole of things. let's

say particles, you need to have 6.022 × 10²³

particles-> this is known as Avogardro's constant

and acts as the definition of the mole.

So, in one mole of nitrogen gas you have 6.022 × 10²³

molecules of nitrogen gas, N². But since each individual

molecules consists of 2 atoms of nitrogen, the number of

moles of nitrogen atoms will be twice that of

nitrogen gas molecules.

6.022 × 10²³ molecules N² × 2 atoms of N / 1 molecules N²

= 1.2044 × 10²⁴ taoms of N

Alternatively, you can express this as 2 × Na,

Where Na is Avogardro's constant. ...
