kingkey24 Posted March 8, 2012 Share Posted March 8, 2012 (edited) so im writing up a pre-lab for class and we have to find the mmol of various compound and i always get stuck when the measurement of compounds are in mL i have NaOCl (sodium hypochlorite) the FW is 77.44 g/mol and density is 1.083 g/mL..... we are using 18 mL of it. can someone help me out???? P.S. the experiment is the oxidation of borneol to camphor Edited March 8, 2012 by kingkey24 Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted March 8, 2012 Share Posted March 8, 2012 NaOCl is a solid and I somewhat doubt you are using ionic liquids in class. You would be using a solution of some sort, so your question really doesn't need density but does require that you know the concentration of your solution.

hypervalent_iodine Posted March 8, 2012 Share Posted March 8, 2012 Are we talking w/w % or w/v %? Link to comment Share on other sites More sharing options...
galaxysponge Posted March 8, 2012 Share Posted March 8, 2012 Multiply your volume by the density to cancel out the mL and get just grams. The divide that amount of grams by the molar mass of the compound to cancel out grams and get moles so im writing up a pre-lab for class and we have to find the mmol of various compound and i always get stuck when the measurement of compounds are in mL i have NaOCl (sodium hypochlorite) the FW is 77.44 g/mol and density is 1.083 g/mL..... we are using 18 mL of it. can someone help me out????

Incidentally, the "6%" might well be "available chlorine" rather than hypochlorite. Link to comment Share on other sites More sharing options...
