Asample of 0.8214 g of kmno4
was dissolved in water and made up to the volume in a 500 ml volumetric flask. a 3.000 ml sample of this
solutions was transferred to a 100 ml volumetric flask and diluted to the mark with water. next, 10.00 ml of the
diluted solution were transferred to a 50 ml volumetric flask and diluted to the mark with water. calculate the
concentration (in molarity) of the final solution.
