Consider this sentence:
There is just one chip left in the bag.
Is this sentence correct? Chips is the usual term used for the entire amount. I feel that it is a plural-only word, similar to money and water which are non-countable.
But it obviously is countable, so maybe better comparisons are bread and cake where we can say a slice of bread and a piece of bread.
Is it possible to say the above sentence and use the word chip? If not, is another singular form then possible?
