Question

Define mole what is the value of avagadros constant

Answer 1

a mole is a unit of measurement, such that onemole of a substance contains 6.022 x 1023 particles. Inchemistry, particles can be atoms, molecules, orcompounds. Conveniently, one mole of a substance has a mass that is equal to its atomic mass expressed in grams.
value of Avogadro constant = 6.022 × 10 23

Answer 2

Answer:

Avogadro's number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.022140857 × 10^23
