SiO2 + C  --> Si + CO2


Mr SiO2 = 28 +16 +16 = 60 gram
2 ton itu 2000 kg (2000000 gram)

Mol SiO2 = 2000000 / 60 = 33.333,33 mol

SiO2 + C --> Si + C

SiO2 = 33.333,33 mol
Si = 33.333,33 mol 
(Perbandingan koefisiennya sama sama 1)


Ubah mol Si jadi gram

Massa = Ar * Mol = 33.333,33 * 28 = 933.333,333 gram

Massa silikon kira kira adalah 933.333,333 gram
