A syringe with a movable piston, contains 0.057g of carbon dioxide gas at 23.5C. If the pressure in the syringe was 953mmHg, what would be the volume of the gas in the syringe?
I got 2.59L, but it was wrong.
Do you have any idea how large a volume 2.59 L is? Something like 2.5 quarts.
moles = grams CO2/molar mass CO2. Then use PV = nRT. Don't forget to use Kelvin for T (K = 273 + C). Also, don't forget to convert 953 mm to atmospheres. (953 mm x (1 atm/760 mm = ??).
