Some Basic Concepts of Chemistry — Class 11 ISC Chemistry revision notes
A 5-page visual revision sheet for Some Basic Concepts of Chemistry, written for Class 11 ISC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Some Basic Concepts of Chemistry sheet covers

- mole concept
- molar mass
- The mole: four doors into the same number
- from mass
- from particles
- from gas volume at STP
- from a solution
- the definition itself
- What a mole is, and what it is not
- Percentage composition, and the two formulas
- Stoichiometry, read off a balanced equation
- Concentration, five ways of saying how much is dissolved
- molarity M
- molality m
- mole fraction x
- mass per cent
- parts per million
- on dilution
- Percentage yield, and why it is never 100
- Equivalent mass and normality, the older bookkeeping
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Some Basic Concepts of Chemistry the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
