How many moles of PCls can be produced from 26.0 g of P4 (and excess Cl2)? Express your answer to three significant figures and include the appropriate units.

"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"
