What is the density of carbon dioxide gas at -25.2°c and 98.0 kpa? a. 0.232 g/l ob. 0.279 g/l oc. 0.994 g/l od. 1.74 g/l o e. 2.09 g/l

E.

Explanation:

From the ideal gasses equation we have:

PV=nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

The number of moles is also expressed as:

If replacing this in the ideal gasses equation we have:

If we pass V to divide, we have:

And the density d = , so replacing, we have:

Solving for d, we have:

Now we have to be sure that we have the correct units, so we need to convert the units for pressure and temperature:

-Convert P=98kPa to atm

-Convert T=-25.2°C to K

Finally we can replace the values in the equation:
