More about this book
Most students read the textbook once and run out of time for a second revision. This formula sheet book is made for that gap: it keeps only what the exam asks, in the same order as the NCERT chapters, so you can revise the full syllabus three or four times before the exam.
Ordering: pay online to get 10% off and free delivery. Cash on delivery is available for ₹80 extra.

CHEMISTRY · UNIT 1120
1.2 EXPRESSING CONCENTRATION OF SOLUTIONS
The amount of solute present in a given quantity of a solution, or of solvent, is called the concentration of the solution. Words such as 'dilute' and 'concentrated' give a rough idea of this amount but are of little use in the laboratory or in industry, where exact quantities are needed. Several quantitative methods of expressing concentration are therefore in use, and the choice among them depends on the purpose for which the solution is prepared.
The simplest of these is the mass percentage, which states the mass of a component present in every hundred units of mass of the solution.
Mass % of a component = (mass of component / total mass of solution) × 100
Thus a solution labelled '10% glucose by mass' contains 10 g of glucose in every 100 g of solution, that is, 10 g of glucose dissolved in 90 g of water. In a similar manner, volume percentage relates the volumes of a liquid solute and of the solution, and mass by volume percentage gives the mass of solute in 100 mL of solution. For very small amounts, as with pollutants in water, parts per million is used. Mole fraction, molarity and molality express concentration in terms of the number of moles of solute and are the most useful in calculations.
