SUMMARY
To prepare 450.0 mL of a 145 ppm potassium ion (K+) solution, the density of the solution is 1.01 g/mL, and the concentration of K2SO4 is 0.728 M. The required volume of K2SO4 solution can be calculated using the formula: volume = (mass of K+ needed) / (concentration of K2SO4 in mol/L). This involves converting ppm to grams and then to moles to find the necessary volume of the K2SO4 solution.
