I am having issues regarding the dilution for a w/v % for an ICP we are reporting as mg/L
I am diluting 10g/100 then further to 1:500 dilution, another chemist that I work with is insisting that the this should be a w/w% for a mg/L result, and has diluted with 10ml/100 to a 1/500 dilution. te density is not 1 and i have tried to explain this to them, with dismal results.
am i going mad?? or am i correct with my diluton being w/v%??
