<u>Answer:</u> The amount of heat evolved per mole of sulfuric acid is 78104.7 Joules.
<u>Explanation:</u>
We are given:
Mass of water =
Mass of sulfuric acid = 10.65 g
To calculate the amount of heat evolved, we use the equation:
where,
m = mass of water + sulfuric acid = [300 + 10.65] = 310.65 g
c = specific heat capacity of mixture = 4.184 J/g.°C
= change in temperature =
Putting values in above equation, we get:
To calculate the number of moles, we use the equation:
Given mass of sulfuric acid = 10.65 g
Molar mass of sulfuric acid = 98 g/mol
Putting values in above equation, we get:
Calculating the heat released per mole of sulfuric acid, we get:
Hence, the amount of heat evolved per mole of sulfuric acid is 78104.7 Joules.
