One ml of pure water is equal to one cubic cm and is one gram. But Jonie had a sample of one ml of pure water but its mass was slightly more than a gram. How can this be?
Hint
The scale she used was accurate and she found the exact mass of the beaker then subtracted it from the total.Answer
She had heavy water. Heavy water is pure water that is slightly heavier. Normal water has two hydrogen atoms and an oxygen atom. Hydrogen has one proton and one electron, but no neutrons. Heavy water is water with at least one hydrogen atom having one neutron.Hide Hint Show Hint Hide Answer Show Answer
