Question

Approximately how many moles of chlorine make up 1.79 × 1023 atoms of chlorine?

Answer 1

Answer:

0.297mol Cl

Step-by-step explanation:

To convert from atoms to moles we must divide the amount of moles by Avagadro’s number.

1.79 x 10^23 atoms / 6.02 x 10^23
= 0.297mol Cl

Answer 2

There are 0.2972 moles of chlorine in
`1.79* 10^(23)` atoms of chlorine.

Step-by-step explanation:

`N=n* N_A`

Where:

N = Number of particles / atoms/ molecules

n = Number of moles

`N_A=6.022* 10^(23) mol^(-1)` = Avogadro's number

We have:

N =
`1.79* 10^(23)` atoms of chlorine

n =?

`n=(N)/(N_A)=(1.79* 10^(23))/(6.022* 10^(23) mol^(-1))`

n = 0.2972 moles

There are 0.2972 moles of chlorine in
`1.79* 10^(23)` atoms of chlorine.
