Finding Molar Mass
This post will continue from the last post and go into a little more depth about molar mass for Prelim Chemistry.
Topic: Mole Concept
- Conduct a practical investigation to demonstrate and calculate the molar mass (mass of one mole) of:
- An element
- A compound
- Conduct an investigation to determine that chemicals react in simple whole-number ratios by moles
Molar Mass
Recall, molar mass is the mass of 1 mole of an atom/compounds. You calculate it by summing the individual molar masses of the elements in a compound in stoichiometry ratio, the individual molar masses can be found on the periodic table. This video will go through molar mass in a little more detail.
This video is an example of a practical for molar mass.
Whole Number Ratios in Reactions
This video will show how reactions occur with whole-number ratios with various example questions.
