Explanation:
10% volume by volume (v/v) is 10ml of conc. HCl diluted to 100ml with water. Sigma Aldrich states that its concentrated HCl is 12.1M. Therefore, a 1 in 10 dilution makes it 1.21M
10% weight by volume (w/v) or weight by weight (w/w), that would mean 10g of HCl dissolved in water and diluted to 100ml with the same solvent.
That would work out to 2.743M (RMM of HCl 36.46g/mol)
Most conc HCl bottles come at 37% assay value, that is the industrial standard. Using the Sigma Aldrich concentration of conc. HCl (found above), a 10% assay value HCl would be around 3.3M
