Use the periodic table in the tools bar to answer these questions. how many moles of agno3 are present in 1.50 l of a 0.050 m solution?

m = Solute moles/liters solution moles of solute =

m. Liters of solution moles of solute = 0050 m x 1.50 L = 0075 moles of AgNo3

"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"
