Hi @Diego, the answer to your question is 153.7kJ.

nope! Units are not consistent.
mols H2O = 50/18 = 1.83
Then
mols H2O = 50/18 = 1.83

oops.Hit the wrong button.
moles H2O = grams/molar mass = 50 g/18 g/mol = 2.78
Then q = mass x delta H = 2.78 mols x 40.7 kJ/mol = 113 kJ
moles H2O = grams/molar mass = 50 g/18 g/mol = 2.78
Then q = mass x delta H = 2.78 mols x 40.7 kJ/mol = 113 kJ
