Answer:
No of moles = mass in gram / molar mass
Mass in gram = no of moles× molar mass
Mass in gram = 0.6330× 163.94
103.77 gram
Explanation:
Answer:
Hydrogen bonding
Step-by-step explanation:
The O-H bonds in water are highly polar.
There is an especially strong type of dipole-dipole attraction between the partially positive H atom in one molecule and the partially negative O atom on a nearby molecule.
We call this type of intermolecular force hydrogen bonding.
The strong attractive forces mean that we must supply extra energy to separate the molecules from each other.
Water therefore has an <em>unusually high boiling point
.</em>
Answer: 0.671614483912211
Explanation: A mole is 6.02214076×1023 (also known as the Avogadro number) I hope this helps!
