Amino Acids undergo a kind of acid base reaction within a molecule. The
Amino group acts as a base and accepts proton from
Carboxylic functional group resulting in formation of
Ammonium with positive charge and a negative charge on
Carboxylate. Such molecules containing both positive and negative charges are called as
Zwittor Ions.
Phenylalanine both in Un-ionized and Ionized form is shown below,
Answer:
Formula weight of H₂O molecule is 18.02 amu.
Explanation:
Given data:
Formula weight of H₂O = ?
Atomic mass of H = 1.008 amu
Atomic mass of O = 16.00 amu
Solution:
Formula weight:
"It is the sum of all the atomic weight of atoms present in given formula"
Formula weight of H₂O = 2×1.008 amu + 1×16.00 amu
Formula weight of H₂O = 18.02 amu
Thus, formula weight of H₂O molecule is 18.02 amu.
Answer:
See solution.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to set up the formula for the calculation of the by-mass percentage of the metal:
Thus, we solve for the molar mass of the metal to obtain:
For the subsequent problems, we proceed as follows:
a.
b.
c.
