Answer:
2.57 x 10⁴ ions
Explanation:
Data Given:
no. of moles of ammonium (NH₄) = 4.26 moles
no. of ions of ammonium (NH₄) = ?
Solution:
formula will be used
no. of moles = no. of ions/ Avogadro's number
As we have to find number of ions so rearrange the above formula
no. of ions = no. of moles x Avogadro's number ...........(1)
where
Avogadro's number = 6.022 x 10²³
Put values in the equation 1
no. of ions = 4.26 mol / 6.022 x 10²³ (ions/mol)
no. of ions = 2.57 x 10⁴ ions
So,
There are 2.57 x 10⁴ ions in 4.26 moles of ammonium
