The density of a 38.0 wt% solution of HCl at 20. oC is 1.1885 kg/L. Determine the molarity of the solution at 20. oC. H

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

i do not get it   at all
