1. The LD50 of cocaine is 95.1 mg/kg. Calculate the concentration of a solution, in molarity if they drank 1 liter of it. 100 g / 303.346 g/mol = 0.329 mol of cocaine. 0.329 mol/ 1 L= 0.329 M for molarity. Is this correct? 2. Find one other concentration unit [mass/mass (g/g) or mass/volume (g/ml) percentage, ppm or ppb] that would be toxic to a 85 kg person. Assume the density of a solution of your substance is the same...

A 0.500 g sample of AgCl was mixed with 250 mL sodium chloride solution of unknown molarity. In order to find the molarity of sodium chloride the amount of dissolved silver ion was monitored with an ion selective electrode at 25 C. The electrode registered the concentration of Ag+ ion to be 3.75x10^-8 M. Calculate the concentration of molarity of the NaCl.
