BUT WHICH CAME FIRST???
llitre or 1kg?
Genuinely been bugging me and am sure someone who knows the true definitions of each can confirm. Pretty please.

Seems that the litre was properly defined first.

It should be:
"Hence a gas will have a greater 'DENSITY' if the 'pressure' is increased as the volume is DECREASED. MASS remains constant as the number of gas molecules will be unchanged".

Density = Mass per volume. If volume is constant and more stuff is forced into the container then the "effective" mass of the object is increased.
Is a little poetic license too much to ask?

Dear god my head hurts
So there is a chance that they 500ml can could weigh less and still have 500ml in it ?

Yes. The weight of the liquid doesn't tell you anything directly about the volume unless you know the liquid's density. If the fabric spray was mostly water, then the customer would have a point. But I doubt there is any water in the spray ... as has already been said, the propellant in the can is probably butane. If it is butane, then you'd exepct 500ml of butane to weigh less than 500g because liquid butane is less dense than water.
