						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.
