200 g of solid sodium hydroxide (NaOH) are dissolved in 750 mL of water. What is the concentration of this solution?
Anastaziya [24]

Answer:

6.67 M

Explanation:

Molarity = \frac{mol}{L}

<em>Convert 200g NaOH to moles. Convert 750 mL to L.</em>

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

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

<em>Substitute values into the equation.</em>

Molarity = \frac{5.00025}{0.750}

Molarity = 6.667... M

Molarity = 6.67 M
