d = 1,09 g/cm3 = 1090 g/dm3
M = 98 g/mol - masa molowa H2SO4
Cmol = Cp x d / M x 100%
Cmol = 13 % x 1090 g/dm3 / 98 g/mol x 100%
Cmol = 1,45 mol/dm3
Cp = 13%
masa H₂SO₄ = 98 g/mol
d = 1,09 g/cm³
1,09 g ---- 1 cm³
x g ---- 1000 cm³
x = 1090 g <---- m[r]
1090g ---- 100%
x g ---- 13%
x = (1099g * 13%) : 100% = 141,7 g <---- m[s]
98 g --- 1 mol
141,7 g ---- x mol
x = (141,7g * 1mol) : 98g ≈ 1,45 mol ---> Cm = 1,45 mol/dm³
Dla kwasu siarkowego (IV):
Cp = 13%
masa H₂SO₃ = 82 g/mol
d = 1,09 g/cm³
1,09 g ---- 1 cm₃
x g ---- 1000 cm₃
x = 1090 g <--- m[r]
1090g ---- 100%
x g ---- 13%
x = (1099g * 13%) : 100% = 141,7 g <---- m[s]
82 g --- 1 mol
141,7 g ---- x mol
x = (141,7g * 1mol) : 82g ≈ 1,73 mol ---> Cm = 1,73 mol/dm³
