SnO2 (s) + 2 H2(g) → Sn (s) + 2 H2O (1)
What mass of water is produce when 80.8g of SnO2 are consumed in the reaction above?

Respuesta :

Molar mass of SnO_2:-

[tex]\\ \sf\longmapsto 118+2(16)=118+32=150g/mol[/tex]

  • Given mass=80.8g

[tex]\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:mass}{Molar\:mass}[/tex]

[tex]\\ \sf\longmapsto No\:of\;moles=\dfrac{80.8}{150}[/tex]

[tex]\\ \sf\longmapsto No\:of\:moles=0.5mol[/tex]

1 mol of SnO_2 produces 2mol of water

  • 0.5mol of SnO_2 will produce 0.5(2)=1mol of water
