Question

how many moles of H2O are formed on combustion of 23g of ethane?​

Answer 1

Answer:

CH4+O2⟶CO2+2H2O

Gram molecular mass of CO2 = 12 +2(16) = 44g/mol

From the reaction it is clear that 1 mole of methane on complete combustion produces 44g (1 mole) of carbon dioxide.

Therefore moles of CH4 required to produce 22g of CO2 are:

             =441×22=0.5 mol

Answer 2

Answer:
