Question

2C2H2 (g) + SO2 (g) → 4CO2 (g) +2H2O (l)
Calculate the mass of CO2 produced from the complete combustion of 1.00g of C2H2.
How do you do this?

Answer 1

Is the answer 3.38 grams?

Answer 2

YES! But how did you get there?

Answer 3

You have some amazing knowledge you must pass on to me!

Answer 4

see here 2 moles of acetylene gives 4 mole of carbon dioxide
mean 1 mole of aetylene gives 2 moles of carbon dioxide
convert mole to their molecular weight that is
26.04 gram of acetylene gives 2 * 44.01
1 gram of acetylene gives =(2*44.01)/26.04=3.38

Answer 5

did u understand

Answer 6

Thank you !! :D :D

Answer 7

and yes :)

Answer 8

Here is what I did:
A simple approach.
2 moles of C2H2 give 4 moles of CO2 (g)
1 mole would give 2 moles Of CO2 right?
Now,
1 mole of C2H2=12*2+2 = 26 grams
2 moles of CO2 = 44*2 = 88 grams
so
It means,
26 grams -----------give 88 grams
1 gram---------88/26=3.38 !
Hope you get it!

Answer 9

it is the same as i did sir @DLS
