Jawaban

Jadi volume asam sulfida awal adalah 224 L. (B)

Penjelasan

Diketahui :

  • massa S (s) = 320 gram
  • Ar S = 32g/mol

Ditanyakan volume asam sulfida (H₂S) = ..?

Pertama, Hitung Mol S

mol S = m / Ar = 320 g/(32 g/mol) = 10 mol

Kedua, Hitung Mol H₂S

Neraca Mol (Asumsi : asam sulfida dan O₂ habis bereaksi)

2H₂S + O₂ ==>  2S + 2H₂O

  10          5        

 -10         -5       +10    +10    

                           10       10

Jadi mol H₂S (asam sulfida) = 10 mol

Ketiga, Hitung volume Asam Sulfida (Gas Ideal)

R = 0.082 L.atm/(mol.K)

Kondisi STP itu artinya P = 1 atm dan T = 273 K.

[tex]\boxed{V = \frac{n.R.T}{P}=\frac{10 \times 0.082 \times 273}{1}=224\ L }[/tex]
