snmercer Posted February 26, 2008 Share Posted February 26, 2008 I don't know where to start. Could someone help? A 7.67 M solution of an acid, HX, has a density of 1.192 g/mL. THe acid, HX, has a molar mass of 53.00 g/mol. Determine the concentration of this solution in molality, Xhx(mole fraction of HX), and %w/w(percent by mass). The solvent in this solution is water, H2O. Link to comment Share on other sites More sharing options...
Ozone Posted February 26, 2008 Share Posted February 26, 2008 Do not confuse molaRity with MolaLity. Here, you have both. Check the density of water, the rest should fall into place. Cheers, O3 Link to comment Share on other sites More sharing options...
hermanntrude Posted February 27, 2008 Share Posted February 27, 2008 here's a useful page from wikipedia. It lists all of the concentration measures you referred to Link to comment Share on other sites More sharing options...
thedarkshade Posted February 27, 2008 Share Posted February 27, 2008 Isn't [math]b=\frac{n}{m}[/math] used here? Link to comment Share on other sites More sharing options...
hermanntrude Posted February 27, 2008 Share Posted February 27, 2008 A formula is useless unless you define the terms. Link to comment Share on other sites More sharing options...
