10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL .9% NACL = 9g/1000mL, Ergo = 9000mg NaCl Now we have to figure out how many mEqs of each salt we have. MW of NaCl = 58.5 MW of KCl = 74.5 So, in moles, we have: 1500 KCl / 74.5 = 20.13 mmol KCl 9000 NaCl / 58.5 = 153.85mmol NaCl Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL. So, just add the two together, 20.13 + 153.85 = 174-ish.
