Depends on the value of G....assuming, of course, that we're at non-relativistic speeds...
However, ignoring those, 0.775 Liters of air should weigh 1 gram - if measured in a vacuum...but if we're at sea level, the air displaced equals the volume of the air weighed, so although the mass is still 1 gram, the weight is now zero.
Maybe I should just switch to mustard.
