A sample of a soil was analysed for K+ as follows. A 2.50 g sample of soil was dissolved in acid and diluted to volume in 100 mL volumetric flask. A 10 mL of the resulting solution was transferred by pipet to a 50 mL volumetric flask and diluted to volume. An analysis showed that the concentration of K+ in the final solution was 9.81 ppm. What was the weight percent of K+ in the original soil
