a)
M(C₃H₅(NO₃)₃) = 3*12g/mol + 5*1g/mol + 3*14g/mol +9*16g/mol = 227g/mol
4C₃H₅(NO₃)₃ → 6N₂ + 10H₂O + 12CO₂ + O₂
4*227g-----------6*28g-------------12*44g----32g
11,35g--------------x--------------------y----------z
X= 11,35g*6*28g/(4*227g) = 2,1g
Y= 11,35g*12*44g/(4*227g) = 6,6g
Z= 11,35g*32g/(4*227g) = 0,4g
Wydzieli się 2,1g + 6,6g+0,4g = 9,1g
b)
N₂ d=1,25 g/dm³ V = m/d = 2,1g/1,25g/dm³ =1,68dm³
CO₂ d= 1,96 g/dm³ V = 6,6g/1,96g/dm³ =3,37dm³
O₂ d= 1,43 g/dm³ V = 0,4g/1,43g/dm³ =0,28dm³
c)
objetosci gliceryny:
V = 11,35g/1,6g/cm³ = 7,09cm³
Objetosci gazów
1,68dm³ + 3,37dm³ + 0,28dm³ = 5,33dm³ = 5330cm³
Vgliceryny/Vgazów = 5330cm³/7,09cm³= 752
