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?

Answer 1

Molar mass of SnO_2:-

`\\ \sf\longmapsto 118+2(16)=118+32=150g/mol`

• Given mass=80.8g

`\\ \sf\longmapsto No\:of\;moles=(Given\:mass)/(Molar\:mass)`

`\\ \sf\longmapsto No\:of\;moles=(80.8)/(150)`

`\\ \sf\longmapsto No\:of\:moles=0.5mol`

1 mol of SnO_2 produces 2mol of water

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