Why is ethanol soluble in water but not propane?

Answer : its about the bonding capacity of the molecule

first of all: water is a polar molecule and therefore hydrogen bonding exist within the molecule.
hydrogen bonding is when hydrogen bond with either flourine, nitrogen or oxygen.

ethanol is a polar molecule and there is a hydrogen bonding within its molecule. However, propane is non-polar molecule and dispersion forces is the only intermolecular force that is exist within its molecule.

Due to similar bonding capacity, ethanol is soluble in water.

The answer for this question is d. none of these

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
