If 162.35 g aluminum hydroxide are dissolved in 6750 mL of solution, the concentration of the solution is 0.308M

How to calculate concentration?

The concentration of a solution can be calculated using the following formula:

Molarity = no of moles ÷ volume (L)

However, the number of moles in 162.35g of Al(OH)3 must be calculated as follows:

Molar mass of Al(OH)3 = 78g/mol

no of moles = 162.35g ÷ 78mol

no of moles = 2.08mol

Molarity = 2.08mol ÷ 6.75L

Molarity = 0.308M

Therefore, if 162.35 g aluminum hydroxide are dissolved in 6750 mL of solution, the concentration of the solution is 0.308M.
