What mass is associated with #1*L# of dioxygen gas at #"STP"#?
I am a bit cagy when I quote these values, because there are different standards in each different syllabus......
AS far as I know,
We're asked to find the mass, in
Chemists often use this fact: One mole of an (ideal) gas at standard temperature and pressure occupies a volume of
(The definition of standard temperature and pressure varies slightly depending on usage, but you'll be using this fact most of the time.)
With that being said, we can use the conversion factor
to convert the given
Now that we know the number of moles of
Which, if you wish to round to one significant figure, is simply
