Berapa mol dan berapa atom ( jumlah partikel ) masing masing unsur yg terdapat dalam zat zat berikut a. 4,6 g Na b. 4 g K c. 8 g F22O3 d. 10,3 g Na2Co3 e. 6 g M

L(bil.avogadro) = 6,02*10²³

A.mol= gr/mr = 4,6/mr Na
=4,6/23
=0,2 mol
Jp= mol*L= 0,2*6,02*10²³
=1,204*10²³

B.mol = gr/mr = 4/1
=4 mol
Jp = mol*L
=4*6,02*10²³
=2,408*10²³

C.mol = gr/mr = 8/19
=0,42 mol
Jp =mol* L
=0,42*6,02*10²³
=2,5*10²³

D.mol = gr/mr = 10,3/106
=0,097 mol
Jp= mol* L
=0,097*6,05*10²³
=5,8*10²²

E.mol = gr/mr = 6/24
= 0,25 mol
Jp = mol* L
=0,25*6,02*10²³
=1,5*10²³
