How heavy is one liter of heavy water?

Answer 1

That's going to depend on where it is. It has about one kilogram of mass,

so on Earth, it's going to weigh about 2.205 pounds (9.8 newtons).

It does not weigh one kilogram. If it did, and you took it to the moon, then

you'd have one kilogram of mass that weighs 0.163 kilograms. That would

really be awkward.

Answer 2

One liter of heavy water weighs slightly more than one liter of regular water because heavy water contains deuterium, a heavier isotope of hydrogen. The exact weight can vary, but on average, one liter of heavy water weighs about 1.107 kg.

Answer 3

1,1056 kg at 20 0C
