Mole Day Planning Pack
Molar Mass Bingo
N
Play the game in silence. Give each student a periodic table, calculator and paper for working
out (if needed) before beginning the game.
Ask the question: “what is the molar mass of (insert name to be called out)”.
Allow students time to think and calculate – ask for a signal (such as palm face up on the desk)
when they have finished the calculation.
A student can ask for a hint on each question. The hint gives the formula of the substance in
question.
The first winner is the first person to cross out all of the numbers on their grid.
What is the molar mass of… (in g mol-1)?*
