n = m ÷ Mr m = n × Mr Mr = m ÷ n

🎯 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
