Wie viel Gramm Magnesiumoxid muss man in 1 l Wasser lösen, um eine 0,5 molare Magnesiumhydroxidlösung zu erhalten? Gib deinen Rechenweg an.

answer; i believe the correct answer is (solid gold);

"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"

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

if you're asking what comes out, it's steam.
