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 data:

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

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
