One cubic meter = 1000liters. One mole CO2 = 44.0g (CO2 = 12.0g + 32.0g = 44.0g) One ton contains 22730 moles of CO2 (1,000,000g / 44.0g/mole) One mole is 24.47L (Boyle's law at 25C and 1 atmosphere pressure) Volume of one ton CO2 = 22730moles  24.47L/mole = 556200L = 556.2m. One ton of CO2 occupies 556.2m of volume.

A lot, and it depends on what all you have on your nachos. The chips themselves will have most likely around 30 carbs per serving (and the servings are not big) and then if you add cheese or anything else your adding carbs (unless the cheese is whole pure cheese with nothing added). Lettuce is low in carbs. Tomatoes have a moderate amount of carbs.
