Question

Calculate the amount of water (g) produced by the combustion of 16g of methane.​

Answer 1

Answer:

One mole of CH4 (16 g) on combustion gives one mole of carbon dioxide and 2 moles of water and 2 moles of water = 2 x [2 + 16] = 36 g of water.

Answer 2

Answer:

CH4 + 2 O2 ➡ CO2 + 2 H2O

1 mole methane - giving - 2 mole water

16 g methane - give --- 2 × 18 g water

so ,

16 g methane - give --- 36 g H20
