\(Coi\ n_X = 1(mol) \Rightarrow n_{tăng} = 1.5\% =0,05(mol)\\ \Rightarrow n_{sau\ pư} = 1,05(mol)\\ Gọi\ n_{O_3} = a(mol)\\ 2O_3 \xrightarrow{} 3O_2 n_X = n_{O_2} + a = 1(mol)\\ n_{sau\ pư} = 1,5a + n_{O_2} = 1,05(mol)\\ \Rightarrow 1,5a - a = 1,05 - 1 \Rightarrow a = 0,1 \Rightarrow n_{O_2} = 1 - 0,1 = 0,9(mol)\\ M_X = \dfrac{0,1.48 + 0,9.32}{1} = 33,6(g/mol)\\ d_{X/H_2} = \dfrac{33,6}{2} = 16,8\)
O2: a mol
O3 : b mol
O3 ---------> 3/2 O2
b -> 1,5b
X: a+b
Y: a+1, 5b
Ta có: a+b/a+1,5b = 100/105
=> a = 9 b
Mx = (9b ×32 +b ×48) /( 9b+b) = 336b/10b = 33,6
dx/H2 = 33,6/2 = 16,8
