What is the pH of a solution prepared to contain 155 grams of HCl in 200.0 mL?

Question

Can you tell me how to do it? I can't remember how...

Answer 1

Convert 155 g HCl to moles.
moles = grams/molar mass

Then M = moles/L soln.

Then pH = -log(HCl)

I wonder if you made this up for us to show you how to work a problem on pH because the numbers I get are not realistic.

Answer 2

its a problem on my homework but thanks you for showing my what to do. its much appreciated
