**Volume calculation of one ton CO2**

One ton = 1000kg

One cubic meter = 1000liters

One mole CO2 = 44.0g (CO2 = 12.0g +
32.0g = 44.0g)

One ton contains 22730 moles of CO2 (1,000,000g / 44.0g/mole)

One mole is 24.47L (Boyle's law at 25°C and 1 atmosphere pressure)

Volume of one ton CO2 = 22730moles × 24.47L/mole = 556200L = 556.2m³

*One ton of CO2 occupies 556.2m³ of volume.*

**Height of CO2 on US land surface**

US 1997 CO2 production = 5,456,000,000ton

US volume of CO2 production = 5,456,000,000ton × 556.2m³/ton = 3,035,000,000,000m³

US land surface area 9,158,960km²

Height of CO2 on US land surface = CO2 volume / surface area = 3,035,000,000,000m³ /
9,158,960km²= 33.14cm (about 1.1 feet high)

*Every year the United States emits a 33.14cm high blanket of carbon dioxide
over its land area.*

**Volume CO2 from one gallon of conventional gasoline**

Gasoline density = 2791grams/gallon

Percent carbon by mass = 85.5%

Mass of CO2 from 1 gal of gas = 2.791kg/gal × 85.5% × (44.0g CO2 / 12.0g C) =
8.750kg

Volume of CO2 from one gallon of gas = 0.008750ton × 556.2m³/ton = 4.867m³

*The combustion of each gallon of conventional gasoline produces 4.867m³ or
171.88ft*^{3} of
CO2.

**CO2 and the Washington Monument**

Volume of the Washington Monument = 22026ft³ = 623.7m³

Gallons of gasoline needed to fill the Washington Monument with CO2 = 623.7m³ / (4.867m³/gallon) =
128 gallons

The New Beetle can run about 4000 miles on 128 gallons.

*A New Beetle, driving 12,000 miles, will create enough CO2 emissions to fill up
the Washington Monument three times*
