The key here is remembering the definition of molarity (M). Molarity is moles over volume in liters. As given by the problem, you already have moles and a volume in mL. Once you convert the volume to liters, you can solve for molarity.
750 mL * 1 L ÷ 1000 mL = 0.750 L : In this case, mL units will cancel out and you are left with just liters, the unit we want to solve for molarity.
Now that we have moles and liters, if we divide the number of moles by the number of liters, we will get the molarity.
1.495 moles of LiOH ÷ 0.75 L = 1.993 M.
This would provide us with the answer E.
