When you teach molar mass, do you just throw up example problems? Or, is there a strategy behind the examples you choose?
There isn't a right way to teach students how to calculate molar mass, but there is definitely a wrong way! When you are choosing your examples, make sure that there is a reason behind that example.
Start with a simple example and then build ideas onto that example. Don't just jump in with a polyatomic ion containing compound and think that students will instantly understand molar mass if you just explain it really well. (Pssst....I did that!!!)
So, if you can't start with a polyatomic ion, what type of problem is good to start with?
