Step 1
Data provided:
Concentration of the solution = 8 M or 8 mol/L
Volume of the solution = 750 mL
(L is needed here, not mL) => 1000 mL = 1 L => 750 mL = 0.750 L
--------------------
Step 2
Molarity = moles of solute/volume of the solution (L)
Moles must be cleared from here, therefore:
Molarity x volume of the solution (L) = moles
8 mol/L x 0.750 L = moles
6 moles = moles of solute
Answer: Moles = 6 moles
