It's only a crossword but can someone answer the following,
Unit of mass equal to one litre of oxygen
Thanks.
Assume Standard Temperature 25degC & Pressure (1 atm)---STP
1 gmole of any gas @ STP ~ 23 liter, 1 gmolel of O2 is 32 grams. So 1 liter of O2 @ STP is 32/23 grams.
Under other conditions I could make a liter of O2 weigh anything I want, from a microgram to a pennyweight.
