1000 kg (1 tona) .................. 100%
m.p kg ................................ 60%
= 600 kg ZnS pura
M.ZnS = 65+32 = 97 g/mol ; M.Zn = 65 g/mol
600 kg m kg
ZnS + H2 --> Zn + H2S
97 65
=> m = 600x65/97 = 402,06 Kg Zn obtinut teoretic la 100%... dar la 80%..?
100% .......................... Ct. = 402,06 kg
80% ............................. Cp. = 321,65 Kg Zn
=> n. moli = m/M = 321,65/65 = 4,95 kmoli = 4950 moli Zn
