Find the molarity of a solution containing 12 grams of LiOH in 500 milliliters of solution.

Select one:

a. 2 M

b. 0.04 M

c. 1 M

d. 0.5 M

Option C. 1M

Explanation:

From the question given, we obtained the following dа ta:

Mass of LiOH = 12g

Volume = 500mL = 500/1000 = 0.5L

Molarity = ?

To solve for the molarity, we need to find the number of mole of LiOH.

This can be achieved by:

Molar Mass of LiOH = 7 + 16 + 1 = 24g/mol

Number of mole = Mass / Molar Mass

Number of mole of LiOH = 12/24 = 0.5mol.

Now we can find the molarity as follows:

Molarity = mole / Volume (L)

Molarity = 0.5/0.5 = 1M
