Chemists need a way to count the number of atoms, molecules, or formula units. Atoms are so __________ and there are so ___________ of them that it is impossible to _____________ them __________________. Atoms are so __________ and there are so ___________ of them that it is impossible to _____________ them __________________. Because of this, scientists created a counting number called the _________. Because of this, scientists created a counting number called the _________. The Mole The Mole The mole, abbreviated mol, is _____________________________________ The mole, abbreviated mol, is _____________________________________ ______________________________________________________________ ______________________________________________________________ ______________________________________________________________ ______________________________________________________________ A mole of anything contains _______________________________ representative particles. A mole of anything contains _______________________________ representative particles. A representative particle is any kind of particle, such as an _____________, a _______________, a ______________ __________, an _______________ or an ____________. A representative particle is any kind of particle, such as an _____________, a _______________, a ______________ __________, an _______________ or an ____________. The number 6.02 x 1023 is called ____________________ ______________. The number 6.02 x 1023 is called ____________________ ______________. 1 mol = _____________________________________________________ (just like a dozen = 12 of something) 1 mol = _____________________________________________________ (just like a dozen = 12 of something)
