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)
