Hello everyone, in this question they have asked that what mass of propane must be burned to produce 76 ,000 kj of energy.
00:11
For that they have given chemical reaction that is combustion of propane that is c3h8 is going to be react with 5 moles of o2.
00:23
Here it produce 3co2 plus 4h2o.
00:29
For that they have given enthalpy of reaction that is delta h is equal to 2200 kj per mole.
00:42
So here they have asked that what mass of propane must be burned to produce 76 ,000 kj of energy.
00:50
So here they have given q value that is equal to 76 ,000 kj and enthalpy of reaction they have given that is equal to 2200 kj per mole.
01:07
So here they have asked that mass of propane.
01:09
So before that we are going to find out number of moles of propane.
01:13
So for that we have an equation as we know that q is equal to delta h into n where n is equal to number of moles.
01:21
So here in this equation where n represents number of moles of propane...
