Question

How many moles are in 6.73 x 1023 formula units of Ba(OH)2?​

Answer 1

Formula Units and Moles

To convert between moles and formula units, we use Avogadro's Number:
`6.02*10^(23)`

Solving the Question

We're given:

• 
  `6.73 * 10^(23)` formula units of Ba(OH)2

To convert to moles, divide by Avogadro's Number:

`n=(6.73 * 10^(23))/(6.02*10^(23))\\\\n=1.12`

Answer

1.12 moles
