Question

SnO2 (s) + 2 H2 (g) → Sn (s) + 2 H20 (1)

What mass of water is produce when 80.8g of SnO2 are consumed in the reaction above?

Answer 1

19.3g of water

Step-by-step explanation:

molar mass of SnO2 is 118.71+16×2

SnO2----150.71.

150.71g of SnO2--------------2(2+16)g of water

150.71g---------------------------36g of water

80.8g-----------------------------x

cross multiply

150.71×x=80.8g×36g

x=2908.8g²÷150.71g

x=19.3g

19.3g of water will be produced
