Answer:

[NaOH] = 1 M

Explanation:

To determine molarity (mol/L) we:

Convert the mass of solute to moles

20 g . 1 mol / 40 g = 0.5 moles of NaOH

Convert the volume of solution from mL to L

500 mL . 1 L / 1000 mL = 0.5 L

Moles of solute / Volume of solution (L) → Molarity

0.5 mol / 0.5L = 1 M

This solution is 1 M, which means that 1 mol of solute (NaOH) is contained in 1L of solution.
