Explanations:
The formula for calculating the molarity of a solution is expressed as:
[tex]molarity=\frac{mole}{volume}[/tex]Given the following parameters
[tex]\begin{gathered} volume=664mL=0.664L \\ molarity=4.423M \end{gathered}[/tex]Determine the mole of the solution
[tex]\begin{gathered} mole=molarity\times volume \\ mole=4.423\times0.664 \\ mole=2.937moles \end{gathered}[/tex]Determine the mass of NH4Cl
[tex]\begin{gathered} mass\text{ }of\text{ NH}_4Cl=mole\times molar\text{ mass} \\ mass\text{ }of\text{ NH}_4Cl=2.937\times53.491 \\ mass\text{ }of\text{ NH}_4Cl=157.096grams \end{gathered}[/tex]Hence the mass in grams of ammonium chloride is 157.096grams
