Question

Calculati masa de acid sulfuric care contine tot atata hidrogen cat si in 4g de metan(CH4)

Answer 1

In 16 g CH4.........4 g H2
     4 g ................x
⇒x=1 g  H2
In 98 g H2SO4.............2g H2
     y g.........................1g
⇒y=98/2=36 g H2SO4
Unde masa moleculara la CH4 =16 si se gasesc 4 g de H2
In 98 g de H2SO4 se gasesc 2 g de H2
