Answer:

3 M

Explanation:

Given data

  • Moles of sodium hydroxide (solute): 5 moles
  • Volume of solution: 2 liters

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)
