Question

What is the molarity of a solution containing 60. grams of NaOH dissolved in 400. mL of water?

Answer 1

Answer: 3.75 M

Step-by-step explanation:

400 mL = 0.4 L

NaOH has a molar mass of around 40 g/mol.

`(60 grams)/(40 g/mol)` = 1.5 moles

Molarity =
`(1.5 moles)/(0.4 Liters)` = 3.75 M
