Moles are the product of the molar concentration and the volume of the solution. The moles of Ferric chloride is 0.118 moles.
Moles are the smallest unit of the measurement of atoms and molecules. It is calculated by the molar concentration and the volume of the solution.
Given,
Molar concentration of ferric chloride = 0.762 M
Volume of solution = 0.155 L
Moles are calculated as:
[tex]\begin{aligned} \rm Moles &= \rm Molarity \times Volume (L) \\\\&= 0.762 \times 0.155\\\\&= 0.118\;\rm mol\end{aligned}[/tex]
Therefore, 0.118 moles of ferric chloride are present in the sample.
