Study of a solution of hydrobromic acid (HBr) One of the strongest known mineral acids, hydrobromic acid is formed by dissolving
hydrogen bromide gas in H2O; it is used in industrial processes like polymerization,
isomerization, dehydration, hydration, and esterification
Given: McAg) =108g/mol : M (Br) = 80g/mol
1. Molar concentration of HBr
On a bottle of commercial solution of hydrobromic acid, the following information
is noted:
Percentage by mass of hydrobromic acid = 27,2 %
Density =
= 1.49 g/ml
M(HBr) = 81 g/mol
1.1. Demonstrate in a clear and precise reasoning that the molar concentration of the
commercial solution is 5 mol/L
