a) MA = 22.2 = 44(g/mol)
b) \(m_C=\dfrac{44.27,27}{100}=12\left(g\right)=>n_C=\dfrac{12}{12}=1\left(mol\right)\)
\(m_O=44-12=32\left(g\right)=>n_C=\dfrac{32}{16}=2\left(mol\right)\)
=> CTHH: CO2
Trong 1,5 mol khí A chứa
+ 1,5.1.6.1023 = 9.1023 nguyên tử C
+ 1,5.2.6.1023 = 18.1023 nguyên tử O
mCO2 = 1,5.44 = 66(g)
VCO2 = 1,5 . 22,4 = 33,6(l)
