Answer: The number of moles of ammonium nitrate is 0.004 moles.
Explanation:
To calculate the number of moles for given molarity, we use the equation:
[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}[/tex]
We are given:
Molarity of [tex]NH_4NO_3[/tex] solution = 0.125 M
Volume of solution = 32.5 mL
Putting values in above equation, we get:
[tex]0.125M=\frac{\text{Moles of }NH_4NO_3\times 1000}{32.5mL}\\\\\text{Moles of }NH_4NO_3=0.004mol[/tex]
Hence, the number of moles of ammonium nitrate is 0.004 moles.
