Lithium hydroxide is used in alkaline batteries. Calculate the molarity of a solution prepared by dissolving 1.495 moles of LiOH in enough water to give a final volume of 750. mL.

[LiOH] = 1.99M

Explanation:

We can apply this rule of three to determine the molarity of LiOH

Molarity are the moles of solute (in this case, LiOH) that are contained in 1L of solution. Our solution's volume is 750 mL

We convert the volume to L → 750 mL . 1L / 1000mL = 0.750L

Therefore we propose:

In 0.750L we have 1.495 moles of LiOH

In 1L we may have (1 . 1.495) /0.750 = 1.99 moles

Molarity → mol/L
