se afla cantitatea pentru fiecare substanta
n(Au)=1g / 197g/mol = 0.005mol
nr.atomi se noteaza prin N
N(Au) = 0.005 mol * 6.023*10²³ = 0.03*10²³
n(Ag) = 1g/108g/mol =0.009mol
N(Ag) = 0.009 * 6.023*10²³= 0.05*10²³
n(K) = 1g / 39g/mol = 0.025 mol
N(K) = 0.025 mol * 6.023*10²³= 0.15*10²³
n(Hg) = 1g / 201g/mol = 0.0049 mol
N(Hg) = 0.0049 mol * 6.023*10²³= 0.029*10²³
n(Fe) = 1g /56g/mol = 0.017mol
N(Fe) = 0.017 mol *6.023*10²³= 0.1*10²³
n(S) = 1 / 32g/mol = 0.031mol
N(S) = 0.031 mol * 6.023*10²³ = 0.186*10²³
n(C) = 1/12 g/mol= 0.083 mol
N(C) = 0.083 * 6.023*10²³= 0.49*10²³
daca i un calculator mai performant, mai fa o data inmultirile, o sa se schimbe puterile la raspuns
