1. Sabendo que a massa atômica do oxigênio é igual a 16u, calcule a massa molar do ozônio (O3):
a) 48 g/mol b) 16 g/mol c) 64 g/mol d) 32 g/mol e) 128 g/mol

"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"
