C3H8O, M = 60 g/mol
C6H6O2, M = 110 g/mol
2a moli C3H8O + a moli C6H6O2
md = 120a + 110a = 230a g
131,1g/23g = 5,7 moli Na
2a moli 2a moli
C3H7OH + Na --> C3H7ONa + 1/2H2
1 1
a moli 2a moli
C6H4(OH)2 + 2Na --> C6H4(ONa)2 + H2
1 2
(150-md) g (150-md)/18 moli
2H2O + 2Na --> 2NaOH + H2
2x18 2
=> 2a+2a+(150-md)/18 = 5,7
=> 4a+(150-230a)/18 = 5,7
=> 72a+150-230a = 102,6
=> a = 47,4/158 = 0,3
=> 120a = 36g C3H8O
=> 110a = 33g C6H6O2
=> A)
