Question

How many moles are in 3.50 x 10^24 atoms of sodium?

Answer 1

`5.81 moles`

Step-by-step explanation:

One mole of any compound contain
`6.023 * 10^(23)` molecules.

Hence, one mole of sodium containing atoms
`$=6.023 * 10^(23)#`

`$3.50 * 10^ {24} $` atoms containing moles
`$=3.50 * 10^(24) * (1)/(6.023 * 10^(23))$`

`$=0.581 mol$`
