Question on mole..Confused...

Question

A volume of 1000dm3 of methane is burnt in oxygen.

Calculate volume of gaseous products when measured

i)below 100 degree

ii)above 100 degree

thx alot for yr help

Answer 1

1 mole CH4 & O2 --> 1 mole CO2  & 2 molesH2O

the ratio of moles of gases in a reaction is equal to the ratio of volumes of those same gases

----------------------------------

i)below 100 degree water is a liquid:

1 mole CH -->produces -->  1 mole CO2

so 1000dm3 produces 1000dm3 of gaseous products

ii)above 100 degree water is a gas:

1 mole CH4  --> 1 mole CO2  & 2 moles H2O

so 1000dm3 produces 3000dm3 of gaseous products

that's your answers
