Is 600ml eqivilent to 600g

Answer 1

It depends on what liquid we are talking about, 600 ml is a measure of volume equivalent to 600 cm3. If it was water, then it would be 600 ml x 0,988 ml-1kg = 592,8 ~600 g. But other liquids or gases may weigh more or less, as it is only water that has the unique ability to weigh in at ~ 1 g/ml.

(Actually, volume was known and stated before mass, and thus, the mass was stated by using water as a reference; they took 1 dm3 water and weighed it, thus concluding that 1 kg was the same as how much 1 dm3 (1 litre) of water weighed. So it is not water that has a unique ability, it just happened to be chosen amongst all other elemnts as the indicator for mass - perhaps it was chosen because it is so common on our planet and always has been vital to our lives?).
