Question

What is the volume of 4.50 mol of `SO_2` at `STP`?

Answer 1

The molar volume of an ideal gas at `STP` is `22.4` `dm^3`.

Explanation:

If we assume the behaviour of `SO_2` to be ideal, the volume of the given quantity of gas is `4.5xx22.4` `dm^3`. It is likely that `SO_2` would show some deviation from ideality at this temperature, but the value would be good for a first approximation.
