How Stupid is This?

This morning I bought a box of orbit complete chewing gum. Of course I wasn't really thinking about carbs when I got it (must change that mindset), but it's OK 'cos it's sugarfree. Just looking at the box I notice that per 100g there are 60g of carbs - that is absolutely HUGE! Of course I can't work out the carb content because whilst they cleverly give all that nutritional information they don't actually bother to give a weight anywhere on the box so I've no idea what each piece of gum weighs.
