a)
$n_{Cl_2} : n_{O_2} = 1 : 2$
Suy ra :
$\%V_{Cl_2} = \dfrac{1}{1 + 2}.100\% = 33,33\%$
$\%V_{O_2} = \dfrac{2}{1 + 2}.100\% = 66,67\%$
b)
Coi $n_{Cl_2} = 1 (mol) \Rightarrow n_{O_2} = 2(mol)$
$\%m_{Cl_2} = \dfrac{1.71}{1.71 + 2.32}.100\% = 52,59\%$
$\%m_{O_2} = 100\% -52,59\% = 47,41\%$
c)
$M_A = \dfrac{71.1 + 32.2}{1 + 2} = 45(g/mol)$
$d_{A/B} = \dfrac{45}{28} = 1,607$
