If 34.2 g of NaOH are dissolved in water to make a 750 mL solution, what is the molarity of the solution?

Respuesta :

Answer:

1.14 M

Explanation:

First divide the mass of NaOH by the molar mass of NaOH. Then divide by the volume to get molarity.

34.2 g / 39.997 g/mol = 0.855 mol NaOH

0.855 mol NaOH / 0.750 L = 1.14 M NaOH
