So, my friend asked my help with a physics problem, but it looks like I wasn't able to get the right answer. The question shouldn't even be hard, but apparently I'm missing something obvious.

20 deg c

saturated water vapor density of .017314 kg/m^3

.1=x/.017314

find x, current vapor density

and remember that is for 1 m^3

That's exactly what I did. (My numbers are slightly different, 0.01729, but that doesn't make big enough difference)
Next I solved x from 0.6=x/0.01729, subtracted the first from latter one and multiplied it with 60.
What did I do wrong, as the answer is apparently incorrect?

answer?
what units does the answer want?

I got 0.519kg for an answer.
Apparently the answer should be in bar, which to be honest confuses me greatly. (0.589bar to be exact)

hmm, yes to .519

i don't know what to say about the .589 bar... the question asks for a mass, not a pressure

Yeah, my reaction was "dafuq" aswell..
Thanks for your help.
