How many moles at STP are contained in 100 mL of
NH??

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L

Explanation:

Hope this helps :)

"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"

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
