Question

What is the molarity of a solution that is made by dissolving 100.0 grams of lithium hydroxide in 750.0 mL of water?

Answer 1

Answer:

The answer to your question is: 5.6 M

Explanation:

Data

Molarity = ?

mass of LiOH = 100 g

final volume = 750 ml

MW LiOH = 7 + 16 + 1 = 24 g

Formula

Molarity = moles / volume

Process

                            24 g ------------------ 1 mol

                          100 g ------------------   x

                              x = (100 x 1) / 24

                              x = 4.2 moles of LiOH

Molarity = 4.2 / 0.750

Molarity = 5.6 M
