Answer : The energy involved in condensation is, 339 kJ
Explanation :
Formula used :

where,
q = heat required = ?
L = latent heat of vaporization of water = 
m = mass of water = 150 g
Now put all the given values in the above formula, we get:


Therefore, the energy involved in condensation is, 339 kJ
31
A dalton is the same as an atomic mass unit. And an atomic mass unit is approximately the mass of a nucleon (proton or neutron) such that the mass is 1 g/mol. So in this problem you have 15 protons and 16 neutrons, so the number of daltons is 15 + 16 = 31.
