Question
How many joules of heat are needed to completely vaporize 24.40g of H2O at its boiling point. Delta H vap = 40.6kJ/mol
Answers
hos many mols do you have? That's mols = grams/molar mass = ?
Convert kJ/mol to J/mol
Then mols H2O x heat vap(in J/m) = q
Convert kJ/mol to J/mol
Then mols H2O x heat vap(in J/m) = q
