What volume of gas is produced by vaporizing a given volume of dry ice?
- What volume of carbon dioxide gas would be released from a one cubic centimeter cube of dry ice at room temperature?

How many grams of CO2 are in one cc of dry ice? The density of dry ice is about 1.5 g/mL, so
1 cc is about 1.5 g CO2.
- How many moles of CO2 are in that number of grams? The molecular weight of CO2 is about 44 g/mol,
so 1.5 g is
1.5 g CO2 × |
( | 1 mol CO2 44 g CO2 | ) |
= 0.034091 mol CO2 |
- What volume of gas contains that many moles of gas? Assume that the gas behaves ideally. At room pressure (about 1 atm) and temperature (about 25°C, or 298 K),
V = nRT/P V = (0.034 mol × 0.0821 L atm mol-1 K-1 × 298 K)/(1 atm) V = 8.3 × 10-1 L
