Calculate the grams of H2O formed when 8g of CH4 burns in excess of oxygen:
- A
21 grams
- B
19 grams
- C
18 grams
- D
15 grams
8/16 = 0.5 mol of CH4
1 mole of CH4 yields 2 moles of H2O, so 0.5 mole will yield 1 mole of H2O.
Mass = mol x Mr = 18 x 1 = 18g
Hence, option C is the only right answer.
As per given calculations, C is the right option.
