2, because they are all a form of water.. but just in different states of matter depending on their form
Answer: C) 0.020 m
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,
n = moles of solute
= weight of solvent in g
Mole fraction of
is =
i.e.
moles of
is present in 1 mole of solution.
Moles of solute
= 
moles of solvent (water) = 1 -
= 0.99
weight of solvent =
Molality =
Thus approximate molality of
in this solution is 0.020 m
I don't get what you are saying... Can you reword it?
Avogadro's law states that in a mole of any substance, there are
atoms. This means that in the given sample, there are

- The atomic mass of sulfur is 32.06 amu.
- The atomic mass of oxygen is 15.9994 amu.
So, the atomic mass of sulfur dioxide is

Therefore, the mass is:

Noble gases are supposed to be the least reactive elements so I’m assuming Neon would be the most least reactive out of all of them.
