1.2702g of a dry solid sample containing an unknown amount of Ru⁶⁺ was dissolved in aqueous solution and made up to the 250ml mark. 20.0ml of this solution were further diluted to 50ml. A current reading of 151.2μA was obtained for this latter solution. Using a linear graphical method, calculate the percent-by-weight (%w/w) of Ru⁶⁺ in the unknown solid sample.
