Volume of gas from given weight of dry ice?
Dry ice, frozen CO2 is sold by the pound. I'd like to know by working formulas, how much volume a pound of dry ice will fill once it returns to gas.
Carbon has molecular weight ~ 12. Oxygen ~16. But I don't recall what those numbers represent.
One mole of gas occupies 22.4 liters, but how much does a mole of CO2 weigh?
