Ways to tell them apart:
A while is two words and is a noun phrase, which typically follows a preposition, like for or in.
Awhile is one word and is an adverb, meaning for a period of time.
Remember, awhile cannot follow a preposition, while a while usually does.
If you can replace the phrase with for a short time and it makes sense, awhile is likely the right choice.
Try swapping a while with a long time to check if the sentence remains correct; if it does, a while is needed.
