Mole concept – for the Year Ones

Today I started a JC 1 class revising secondary 4 work on mole concept and calculations.

For the stronger Chemistry students, this chapter might seem easy to handle, which is a good thing. However, do not be complacent, and always be alert with calculations.

It is easy to make careless mistakes and overlook the number of  zeroes and decimal place.

Also, the mole reacting ratio can be rather challenging at times.
