\(\dfrac{12x}{\%C}\)=\(\dfrac{y}{\%H}\)=\(\dfrac{14t}{\%N}\)=\(\dfrac{MA}{100}\)
MA tỉ khối hơi vs H2 ⇒MA =81.2=162
⇒\(\dfrac{12x}{74,07\%}\)=\(\dfrac{y}{8,64\%}\)=\(\dfrac{14t}{17,28\%}\)=\(\dfrac{162}{100}\)
⇔ \(\dfrac{12x}{74,07\%}=\dfrac{162}{100}\Rightarrow x=10\)
\(\dfrac{y}{8,64\%}=\dfrac{162}{100}\Rightarrow y=14\)
\(\dfrac{14t}{17,28\%}=\dfrac{162}{100}\Rightarrow t=2\)
