How many ions are in 4.26 moles of ammonium

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

i would say b

explanation:

but i think i would need more information than that

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
