Explanation:
First, we will calculate the molar mass of as follows.
Molar mass of =
= 78 g/mol
So, when 2 mol of burns, then heat produced = 6542 KJ
Hence, this means that 2 molecules of are equal to
of
burns, heat produced = 6542 KJ
Therefore, heat produced by burning 5.5 g of =
= 228.97 kJ
= 228970 J (as 1 kJ = 1000 J)
It if given that for water, m = 5691 g
And, we know that specific heat capacity of water is 4.186
.
As, Q =
228970 J =
Thus, we can conclude that the final temperature of the water is .
