Calculate the molarity of a % 1.00E-3 by mass crystal violet solution assuming at this concentration the density of the solution is 1.00 g mL-1 and molar mass of crystal violet is 407.98 g mol-1.
Calculate the molarity of a solution created, when 1.00 mL of the solution described in question above is mixed with 0.200 mL of 1.00 M NaOH (assume that a reaction hasn’t started).
