Question

Assuming it behaves as an ideal gas, calculate the density of sulfur dioxide, so2, at stp.

Answer 1

Hello!

At Standard Pressure and Temperature, an ideal gas has a molar density of  0,04464 mol/L.

So, we need to apply a simple conversion factor to calculate the density of Sulfur Dioxide using the molar mass of Sulfur Dioxide.

$\frac{0,04464 mol SO_2}{1 L SO_2}* \frac{64,066 g SO_2}{1 mol SO_2}=2,8599 g/L$

So, the Density of Sulfur Dioxide (SO₂) at STP is 2,8599 g/L

Have a nice day!

Answer 2

Answer:

2.86 g/L

Explanation:

Density can be defined as the ratio of mass to volume, that is, Mass/volume.

The molar mass of sulfur dioxide, SO2 can be calculated and it is given as: 32.07 + (16×2) = 64.07 grams per mole.

At standard temperature and pressure(step), one mole of an ideal gas is equal to the volume 22.4 litres. Hence, the gas density can be calculated using the formula below;

Density of sulfur dioxide,SO2 at stp= [molar mass(in grams per mole)÷ 1 mole] × [ 1 mol÷ 22.4 litres] ----------------------------------------------(***).

substitute in the values into the equation above, we have;

==> (64.07 grams per mol/ 1 mol) × 1 mol/22.4 litres.

===> 2.8603 grams per litre.
