Answer:
2 mole H2O = 18.02 g will not work.
Explanation:
Let us check the options one by one:
1 mole of O2 weighs 32 g.
⇒Hence option A is correct.
1 mole of H2O weighs 18 g.
⇒Hence option B is wrong.
From the balanced equation we can say :
1 mole of CH4 reacts with 2 moles of O2 to give 1 mole of CO2 and 2 moles of H2O.
⇒Hence option C and D are correct.
