Question

Tính tỉ khối của các khí sau so với khí nitơ: H2S ,O2, H2, CO2

Answer 1

$d_{H_2S/N_2} = \dfrac{34}{28} = 1,2$
$d_{O_2/N_2} = \dfrac{32}{28} = 1,14$
$d_{H_2/N_2} = \dfrac{2}{28}= 0,07$
$d_{CO_2/N_2} = \dfrac{44}{28} = 1,57$

Answer 2

\(d_{H2S/N2}=\dfrac{M_{H2S}}{M_{N2}}=~2,43\)

\(d_{O2/N2}=\dfrac{M_{O2}}{M_{N2}}=~1;14\)

\(d_{H2/N2}=\dfrac{M_{H2}}{M_{N2}}=~0,07\)

\(d_{CO2/N2}=\dfrac{M_{CO2}}{M_{N2}}=~1,57\)
