According to Arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. Further, acid and base reacts to form salt and water.
Consider following example.
HCl + H2O → Cl- + H3O+
here, HCl has donated a proton, hence it is an acid.
Now consider following reactionHCl + NaOH ↔ NaCl + H2O
in this reaction, HCl donates proton, hence it is acid. On other hand, NaOH donates hydroxyl ion (i.e. OH-), hence it is a base.

Answer:
<h2>mass = 19.98 g</h2>
Explanation:
To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula
<h3>m = M × n</h3>
where
m is the mass
M is the molecular mass
n is the number of moles
From the question
n = 1.11 mol
Taking
M( H) = 1 g/mol , M(O) = 16 g/mol
We have
M( H2O) = 2 + 16 = 18 g/mol
So we have
m = 1.11 × 18
We have the final answer as
<h3>mass = 19.98 g</h3>
Hope this helps you
