Molecular weight of HBr = 80.91 g/mol.
We know that, 1 mole of HBr = 80.91 g/mol
Therefore, 2 mole of HBr = 80.91 x 2
= 161.82 g.
Hence,
161.82 g
of HBr should be dissolved in 1 liter solution, to obtain 2 M solution.

1. Titrations are generally both more accurate and more precise the smaller the concentration of titrant you use. A 6.0 M NaOH stock solution is provided by the stock room. (a) What volumes of the stock
