4) Calculate the molarity of a solution prepared by dissolving 32.9 g of NaOH in enough water to
make 700.0 mL of solution.
What the molarity

Respuesta :

Answer:

1.175 M

Explanation:

Mass =  32.9 g

Volume = 700.0 mL = 0.7 L

Molarity = ?

The relationship between the quantities is given by;

Molarity = Number of moles / Volume

Number pf moles = Mass /Molar mass

Number of moles = 32.9 / 40 = 0.8225 mol

Molarity = 0.8225 / 0.7 = 1.175 M
