Use PV = nRT
n = moles CO2 = grams/molar mass. Don't forget T is in Kelvin.
A piece of dry ice (solid carbon dioxide) with a mass of 25.5 g is allowed to sublime (convert from solid to gas) into a large balloon.
Assuming that all of the carbon dioxide ends up in the balloon, what will be the volume of the balloon at a temperature of 18 degrees Celsius and a pressure of 745mmHg?
