Find the number of moles in 25.0g of ammonium

1.389 moles

Explanation:

We are given that

Given mass of ammonium=25.0 g

We have to find the  number of moles in 25.0g of ammonium.

The chemical formula of ammonium

Molar mass of N=14, Molar mass of H=1

Molar mass of ammonium (NH4+)=14+4(4)=18 g/mol

We know that

Number of moles=Given mass/Molar mass

Using the formula

Number of moles of ammonium=moles

Number of moles of ammonium=1.389 moles

Hence, the number of moles in 25.0g of ammonium=1.389 moles
