Answer:

6.67 M

Explanation:

Molarity = [tex]\frac{mol}{L}[/tex]

Convert 200g NaOH to moles. Convert 750 mL to L.

200 g NaOH x (1 mol/39.998 g) = 5.00025... mol NaOH

750 mL x (1 L/1000 mL) = 0.750 L

Substitute values into the equation.

Molarity = [tex]\frac{5.00025}{0.750}[/tex]

Molarity = 6.667... M

Molarity = 6.67 M
