The intermolecular forces (IMF) present in hydrogen bromide (HBr) primarily include dipole-dipole interactions and London dispersion forces. HBr is a polar molecule due to the difference in electronegativity between hydrogen and bromine, leading to a permanent dipole. Additionally, London dispersion forces are present due to temporary dipoles that can occur in all molecules. Overall, the dipole-dipole interactions are the dominant force in HBr.
Ka = [H+].[Br-] / [HBr] However the value of this expression is very high, because HBr is a STRONG acid, meaning that much more than 99.9% of the HBr molecules in water are protolized (ionized), making [H+] and [Br-] equal to the original (added) HBr amount, and the [HBr]-value nearly zero.
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NO·HBr.

For this you need the atomic (molecular) mass of HBr. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. HBr= 81.0 grams186 grams HBr / (81.0 grams) =2.30 moles HBr

The chemical formula of hydrobromic acis is HBr.
In the reaction, HBr donates a proton (H+) to H2O, making HBr the acid and H2O the base. The resulting products are Br- (conjugate base of HBr) and H3O+ (conjugate acid of H2O).
This compound is HBr.

Polar!
HBr is not a weak base; it is a strong acid. In water, HBr completely dissociates into H+ and Br- ions, leading to a high concentration of H+ ions in solution. This strong acidity makes HBr a poor proton acceptor and hence not a base.
