Question

What is the concentration (in M) of a solution that was prepared by dissolving
42.792 g of NAOH in a 375.0 mL solution?
Your Answer:
Answer
units

Expert Solution

Step 1

1- First calculate the moles of NaOH :

moles = [ mass / molar mass of NaOH ]

moles = [ 42.792g / 40.0gmol-1 ]

moles = 1.07mol of NaOH

Step by step
