what is mole concept
Answers
Answer:
The mole concept is a convenient method of expressing the amount of a substance. Any measurement can be broken down into two parts – the numerical magnitude and the units that the magnitude is expressed in. ... It primarily focuses on the unit known as a 'mole', which is a count of a very large number of particles.
Answer:
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter. A mole is defined as the amount of substance containing the same number of discrete entities (atoms, molecules, ions, etc.)
Formula
Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
Molarity
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.
Weight
A mole is the atomic weight of a molecule of the chemical in grams. So a mole of a molecule like hydrogen (H) with an atomic weight of 1 is one gram. Meanwhile, a complex molecule like glucose (C6H12O6) has an atomic weight of 180, so one mole is 180 grams.
