Does this sound right to you? Surely if you have a singular noun, the number is always going to be one, so "the number of" would never arise.
Sorry - I moved the prior post to its own thread, but just as I was doing so, Raymott replied. Quoting his response was the easiest fix I knew.
EDIT: Okay, I figured out how to get the response attached to the original question now.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
