How many moles of ammonium nitrate are there in 32.5 mL of<br> a0.125 M NH4NO3 solution?
Nady [450]

<u>Answer:</u> The number of moles of ammonium nitrate is 0.004 moles.

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}

We are given:

Molarity of NH_4NO_3 solution = 0.125 M

Volume of solution = 32.5 mL

Putting values in above equation, we get:

0.125M=\frac{\text{Moles of }NH_4NO_3\times 1000}{32.5mL}\\\\\text{Moles of }NH_4NO_3=0.004mol

Hence, the number of moles of ammonium nitrate is 0.004 moles.
