Un liquide organique à pour formule brute C,H,O₂. On en vaporise 0,018 g dans un Q₂ no eudiomètre contenant un excède dioxygène (voir figure). Après passage de l'étincelle électrique, on trouve que la combustion a nécessité 30,8 cm³ de dioxygène et donné 22,4 cm³ d'un gaz absorbable par la potasse, les volumes gazeux étant mesurés dans les conditions normales. La densité de vapeur du composé est voisine de d = 2,48.

1) Eerire l'équation de la combustion.

2) Déterminer x, y et z et écrire la formule brute du composé.

3) Calculer la masse d'eau recueillie.
M(C) = 12 g/mol; M(O)-16 g/mol; M(H) = 1 g/mol On rappelle que la potasse absorbe le dioxyde de carbone.
