Bài 1:
\(n_{O_2}=\dfrac{22.4}{22.4}=1\left(mol\right)\)
\(C_nH_{2n+2}+\dfrac{\left(3n+1\right)}{2}O_2\underrightarrow{t^0}nCO_2+\left(n+1\right)H_2O\)
\(1.................\dfrac{3n+1}{2}\)
\(0.2................1\)
\(\Rightarrow0.2\cdot\dfrac{3n+1}{2}=1\\ \Rightarrow n=3\)
\(CT:C_3H_8\)
Bài 2 :
Giả sử : nC4H10 = 1 (mol)
Theo BTKL: m5 hiđrocacbon = mC4H10ban đầu = 58 gam
=> n5 hiđrocacbon = 58/(16,325 * 2) ≈ 1,7764 mol
=> nC4H10phản ứng = 1,7764 - 1 ≈ 0,7764 mol=> H ≈ 77,64%
