Dear students, as for the question, hexane is 0 .315 mole, water 5 .65 liter, change in temperature is 55 .4 degrees celsius and density of water is 1 gram per ml.
00:13
Now here, volume is constant.
00:15
As for the question, volume is constant.
00:20
Therefore we have to find out enthalpy of combustion of hexene per 1 mole of hexon.
00:26
We know q is equal to ms delta theta, that is heat evolved is equal to mass, the temperature, of the substance multiplied by specific it multiplied by change in temperature.
00:35
Here mass of water is not given but volume is given.
00:38
Therefore we can find out mass of water in the calorimeter equal to 5 .65 liter.
00:47
So we'll multiply by thousand to convert it into gram multiplied by density that is 1.
00:52
So it is 5 .5650 gram which is nothing but 5...
