An uninflated balloon full of air has a volume of 300.0 mL and contains 0.0240 mole of air. A 2.00 g piece of dry ice (solid CO2) is placed in the vessel and sealed. What is the volume of the balloon after the dry ice has vaporized? Assume constant temperature and pressure. Also, assume no change in the initial amount of air.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
