In summary, the density of sulfur dioxide (SO2) is approximately 2.927 g/L at standard temperature and pressure (STP). It can be measured using various methods, including gas density meters, pycnometers, and density gradient columns. The density of SO2 can be affected by temperature, pressure, and the presence of other gases. It is typically measured in units of g/L at STP, but can also be expressed in other units such as kg/m3 or lb/ft3. Knowing the density of sulfur dioxide is important for scientific and industrial purposes, such as in the production of sulfuric acid and air pollution monitoring. It also helps in understanding its behavior in the environment and potential impact on human health.

Looks like a mistake in the text.
We do have that $\ce{SO4^2-}$ has molar mass of $96.1\,\text{g/mol}$, so I think someone mixed up sulfur dioxide and sulfate.

## 1. What is the density of sulfur dioxide?

The density of sulfur dioxide (SO2) is 2.927 g/L at standard temperature and pressure (STP), which is 0°C and 1 atmosphere pressure.

## 2. How is the density of sulfur dioxide measured?

The density of sulfur dioxide can be measured using a variety of methods, including gas density meters, pycnometers, and volumetric glassware. These methods involve measuring the mass and volume of a known amount of SO2 to calculate its density.

## 3. Does the density of sulfur dioxide vary with temperature and pressure?

Yes, the density of sulfur dioxide is affected by changes in temperature and pressure. As the temperature increases, the density of SO2 decreases. Similarly, as pressure increases, the density of SO2 also increases.

## 4. What are the units for measuring the density of sulfur dioxide?

The density of sulfur dioxide is typically measured in grams per liter (g/L) or kilograms per cubic meter (kg/m3). However, other units such as pounds per cubic foot (lb/ft3) may also be used.

## 5. Why is the density of sulfur dioxide important?

The density of sulfur dioxide is important because it is a key factor in determining the behavior and effects of this gas in the environment. It can impact air quality, human health, and the formation of acid rain. Additionally, the density of SO2 is used in various industrial processes and in the production of sulfuric acid.
