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...
