Question

Calculate how many gr of water produced by combustion of 16 gr of methane?​

Answer 1

Answer:

we know when methane reacts with oxygen to forms carbon dioxide and water , so it's very easy for us to solve it nicely

~ 1 CH4 + 2O+ CO 2 + 2H2O

here,

• 16 gms of methane is equal to one mole  [ by the formula ]

~ And the main point is that 1 mol of methane gives 2 mol of water isn't it ?

To find the mol in any equation just see the times of any compound

for ex:-

2H2O has 2 mol because it is multiplied with 2 . and same for others too

2 Mol of water ( H2O ) = 2 × ( 2 + 16 ) = 36 gms

1 mol of water = 18g × water
