3kmoli 227kg 3*18kg
C₆H₅-CH₃ + 3HNO₃ -> C₆H₂CH₃(NO₂)₃ + 3H₂O
x=? 22,7kg y=?
x=22,7*3/227=0,3kmoli HNO₃ => 0,6kmoli H₂SO₄
y=5,4kg apa
Insa noi mai avem o cantitate a de apa.
5,4+a=2a => a=5,4kg apa
mHNO₃=0,3*M HNO₃=0,3*63=18,9kg HNO₃
mH₂SO₄=0,6*M H₂SO₄=0,6*98=58,8kg H₂SO₄
mamestecnitrant=mHNO₃+mHNO₃+5,4kg=18,9*58,8+5,4=83,1kg amestec sulfonitric
