Explanation:
Reaction equation:
HBr + Al(OH)₃ ⇒ H₂O + AlBr₃
To balance an equation we make sure that the same number of atoms appears on both sides of the expression.
HBr + Al(OH)₃ ⇒ H₂O + AlBr₃
Let us a simple mathematical method to solve this problem
aHBr + bAl(OH)₃ ⇒ cH₂O + dAlBr₃
a, b , c and d are the coefficients that will make the equation balanced;
Conserving H; a + 3b = 2c
Br; a = 3d
Al; b = d
O; 3b = c
let us make a = 1
d =
b =
c = 1
multiply through by 3;
a = 3, b = 1, c= 3 and d = 1

The average atomic mass of hydrogen (99% H-1, 0.8% H-2, and 0.2% H-3) is 1.012 amu.
The average atomic mass of hydrogen can be calculated with the following equation:
Where:
: is the mass of protium (H-1) = 1
: is the <em>mass</em> of deuterium (H-2) = 2
: is the <em>mass </em>of tritium (H-3) = 3
: is the abundance percent of H-1 = 99%
: is the <em>abundance percent</em> of H-2 = 0.8%
: is the <em>abundance percent</em> of H-3 = 0.2%
The average atomic mass is:
Changing all the <u>percent values</u> into <u>decimal ones</u>, we have:
Therefore, the average atomic mass of hydrogen is 1.012 amu.
