Calculate the molarity of the following solutions. Calculate the molarity of 23.0 g of NaOH in 330. mL of an NaOH solution.

Answer 1

Answer #1

molarity = moles / volume in liters

no of moles = mass / molar mass

for NaOH = 23g / 40 g/mol => 0.575 moles

volume = 0.330 L

molarity = 0.575 moles / 0.330 L

molarity = 1.74242 moles/L (or) 1.74242 M

answer => 1.74 M
