Question

80.0 grams of NaOH is dissolved in water to make a 6.00 L

solution. What is the molarity of the solution? (Molar mass of NaOH
= 40.0 g/mol)
M М.

Answer 1

0.333 M

Step-by-step explanation:

Divide the mass of NaOH by the molar mass and then divide by the volume.

80.0 g / 40.0 g/mol = 2.00 mol NaOH

2.00 mol NaOH / 6.00 L = 0.333 M NaOH
