S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

In the above equation how many moles of water can be made when 28 moles of HNO3 are consumed?

AND

2 NH3 + 3 CuO g 3 Cu + N2 + 3 H2O

In the above equation how many moles of water can be made when 76 moles of NH3 are consumed?

Respuesta :

#1

  • 2 mol of water is made when 6mol of HNO3 are consumed.

Let moles of water can be made be x

[tex]\\ \sf\longmapsto \dfrac{2}{6}=\dfrac{x}{28}[/tex]

[tex]\\ \sf\longmapsto \dfrac{1}{3}=\dfrac{x}{28}[/tex]

[tex]\\ \sf\longmapsto 3x=28[/tex]

[tex]\\ \sf\longmapsto x\approx 9mol[/tex]

#2

Let moles of water can be made be x

[tex]\\ \sf\longmapsto \dfrac{3}{2}=\dfrac{x}{76}[/tex]

[tex]\\ \sf\longmapsto 2x=76(3)=228[/tex]

[tex]\\ \sf\longmapsto x=114mol[/tex]
