Question

How many ions are in 4.26 moles of ammonium

Answer 1

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
