figuring w/vol %?

[El_Zorro]

How would a bee figure the molar amount of a HCl solution if the given amount is 37% w/vol?  And another thing, does anybody have the density of a 35% formaldehyde solution?

Hmm, 37% w/vol to me implies: 0.37 g HCl/ml of soln

If 0.37 g HCl = 0.37 g/36.46 g/mol = 0.0101 mols HCl

then the molar conc. of the soln is: 0.0101 mols/ml

Molarity means moles per litre if i remember correct.You can do calculations yourself.
