Answer: - 5.00 kJ
Explanation:
1) The heat evolved during the reation is proportional to the number of moles dissolved.
2) Proportionality = ratio is constant
<span>3) δh°soln of HNO3 is –33.3 kJ/mol => ratio 1
-33.3 kJ
ratio 1 = ---------------------
1 mol HNO3
4) ratio 2
x
--------------
0.150 mol
</span>
5) proportion
ratio 1 = ratio 2
x -33.3 kJ
--------------- = -------------- => x = 0.150 mol * (-33.3kJ) / 1 mol = - 4.995 kJ ≈
0.150 mol 1 mol
≈ - 5.00 kJ
