conservación de la masa
- This is problematic because the law of conservation of mass or matter is a unifying scientific principle that students should be able to apply to biology, physics, and chemistry. They may find this difficult if they do not recognize that atoms and molecules are both types of matter, for example.
Among his many notable discoveries were his proposal of the law of conservation of mass, which states that mass is neither created nor destroyed.

Examples
-
Einstein's theory does not contradict the conservation of mass, which remains a fundamental rule of classical physics.
-
Cutting and burning those trees causes all the carbon stored in them to return to the atmosphere, but the belief in existing untouched forest as a carbon sink seems to violate the conservation of mass.

The law of conservation of mass implies that mass can neither be created nor destroyed, which means that our hero's mass will not change just because his size changes.
-
We can codify it in terms of a simple rule that captures the notion of phase separation and conservation of mass and that's called the lever rule.

Given that the HPV rDNA couldn't replicate, the law of conservation of mass is enough to dismiss this concern as ridiculous, because it would take far more DNA than could possibly be in the adjuvant to produce detectable levels in the blood for long periods of time.

Morphology
conservation + of + mass
The meaning is directly composed from 'conservation' (preservation/keeping) + 'of' + 'mass' (amount of matter), so a learner who knows the constituent words can infer it means that mass is preserved in a system. This noun phrase follows a transparent scientific naming pattern common across languages, making the concept derivable without prior exposure.
Etymology
The term conservation of mass comes from a simple image: conservation means keeping something, and mass means the amount of matter. Imagine a closed box where pieces may move or change but the total amount 'stays the same', so the phrase reminds us that the total matter does not change.
