📐 The Mole Triangle — Your Calculator in Disguise
🎯 Cover what you want to find — the other two show you the calculation!
How to use it: Put your finger over what you want to find. The remaining two symbols show you what calculation to do!
- Want moles? Cover n → you see m over Mr → so n = m ÷ Mr
- Want mass? Cover m → you see n next to Mr → so m = n × Mr
- Want Mr? Cover Mr → you see m over n → so Mr = m ÷ n
