It's not a problem for me if you're on board with the CSTEM approach, even if we rebrand a lot of what you called "math" to the "computer science" side of the fence. It's still logs, exponents, half life stuff, but we needed to use a Jupyter Notebook or something like that, in Mr. Urner's classroom. SageMath maybe?
Avogadro's number as a floating point Numeric type object in scientific notation will be one of several constants we keep kicking around (as in "going back to").
How much does one Avogadro's number (one mole) of Cesium137 atoms weigh, in pounds?
If all of them are radioactive to start, in how many years will about half of them have discharged?
You're welcome to look it up online (no penalty for looking up facts about atoms versus memorizing the whole Periodic Table top to bottom).
CSfriendly needn't mean "math unfriendly". On the contrary, the CS emphasis on "type sense" as in "what type of object is this?
This question of type, as in "Integer? Vector? Quaternion?" is the same as "into what set does this object belong?"
I can't think of any math teacher objecting to a growing sense of "membership domains" ala
N < Z < Q < R < C < whatever letter we use for Quaternions (concentric number sets).
