Numbers and amounts
You can talk about one tonne of tar needed to repair a stretch of road. That's an amount, you can weigh it or measure it; you describe it with a unit (e.g. of length, weight etc). You can't talk about one tar, unless you are watching a performance of Gilbert & Sullivan's Pirates of Penzance.
You can talk about one lorry, needed to carry all that tar, because you can count the number of vehicles. Talking about an amount of lorries does not make sense.
