How heavy is a litre of heavy water? -Or should I say, what is it's mass, as
it's a physics question?
-You know, water with deuterium instead of ordinary hydrogen? -At sea level
and room temperature..
Would there be heavy water at the deep parts of the seas? - or is that a
daft question?
Hope you don't mind my asking, I am in a funny mood..

According to http://www.nobel.se/chemistry/laureates/1934/press.html it's
1kg plus 1 hectogramme (?)...

Whereas, as we know, one litre of ordinary water weighs one kilogramme, one
litre of heavy water weighs about one kilogramme and one hectogramme, which
approximately corresponds to the increase in the weight of the molecule. Its
freezing-point is +3.8° instead of 0° (that of ordinary water), and its
boiling-point is 1.4 degrees higher than that of ordinary water. It is more
viscous than ordinary water and the solubility of salts in it is less, etc.,
etc. It has furthermore proved possible either wholly or partially to
replace by heavy hydrogen the ordinary hydrogen that is a constituent of
ammonia, hydrochloric acid, acetic acid, sugar, albumen, etc., etc. As heavy
and light hydrogen thus - in contradistinction to previously known
isotopes - possess different chemical characteristics, it has been thought
advisable to bestow on them individual names. Urey calls heavy hydrogen
deuterium and ordinary hydrogen protium. The reaction velocity for ordinary
hydrogen or ordinary water respectively, as compared with deuterium or heavy
water respectively, has proved to differ on occasion, as has also the
ultimately obtained yield of the reaction. Among chemico-biological effects
there may be noted: that alcoholic fermentation proceeds more slowly in
heavy than in ordinary water, that the sprouting of tobacco seeds and the
evolution of yeast fungi are delayed or checked, etc., etc. Atomic nuclei of
heavy hydrogen, when propelled as rapid projectiles by an electric field
have proved to be exceedingly effective in the breaking down of atoms and in
transformation of elements in conjunction therewith. Radio-sodium produced
by that process may perhaps prove to be of medicinal importance.

Fist hit on Google for phrase heavy water yields:

http://www.sno.phy.queensu.ca/sno/D2O.html

Find mass of a liter of water. Calculate.

Snipped a lot to prevent paralysis of the mind.

Ok now lets hear what you know about Christmas trees.

Hmm - does half heavy water count as heavy water? (half heavy water =
one regular hydrogen atom, one atom of deuterium and one atom of
oxygen) Then there's also tritium (hydrogen with two protons) although
that's radioactive and emits a beta ray to become helium 3 IIRC.

In nature, there should be far more half heavy water than D2O just as
there is far more hydrogen with no neutrons than deuterium.

Of course, if you buy something called "heavy water" it has been sorta
manufactured - you take regular water and put it in something like a
centrifuge to separate the various varieties of water.

Regular water has a neutron + proton count of 18.
D2O has a n+p count of 20.
Water with one atom of deuterium has an n+p count of 19.

Electrons and the difference in mass between a neutron and proton are
too small to worry about for most purposes.

So it would be 1111 grams/liter for D2O and 1055 for water with only
one Deuterium atom.

So it would cost about \$15,000 to knock off my billionair uncle
