What would the concentration be of a solution made
bydissolving 5 moles of naoh in enough water to make 2 liters
ofsolution.

3 M

Explanation:

Given data

We can calculate the molar concentration, or molarity (M), of the solution using the following expression.

M = moles of solute / volume of solution (in liters)

M = 5 moles / 2 L

M = 2.5 M ≈ 3 M (if we round off to 1 significant figure)

elements make up everything, and they combine to make compounds.

the answer is c
