Question

6 g of ethane (C2H6) is burnt in excess of O2. The moles of H2O formed would be x. The value of 10x is​

Answer 1

Answer:

10x = 6

Explanation:

2C2H6 + 7O2 -----> 4CO2 + 6H2O

now number of mole of ethane burnt = 6/30 = 0.2mole

2 mole ethane on burning gives 6 mole of H2O

1 mole of ethane will give => 6/2 mole of H2O

=> 0.2 mole ethane give => (0.3)×2 mole of H2O

now x = 0.6...{according to questions}

therefore 10x=6
