The mole concept helps in counting atoms and molecules from "summary" of NCERT Chemistry Class 11 - [CBSE Board] by Dr. S. C. Rastogi, ,Er. Meera Goyal
The mole concept is a fundamental concept in chemistry that helps us in counting atoms and molecules. It provides a way to measure the amount of a substance by relating it to its mass. By using the mole concept, we can easily determine the number of atoms or molecules present in a given sample of a substance. In the mole concept, one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. This number is based on the number of atoms in 12 grams of carbon-12, which is defined as one mole. By knowing this number, we can calculate the number of atoms or molecules in any given sample by simply using the formula: Number of particles = Number of mo...
