calculate the amount of solvent that separates as solid when 30gram of saturated solution prepared at 50 degree Celsius is cooled 30 degree Celsius the solubility of the given solute is 35at 50 degree Celsius and 21 at 30degree Celsius​

uranium-238 i believe is your answer

i believe the answer is a.

i'm assuming that the correct answer is indeed the first one/ "a"..

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
