Determine the concentrations of K2SO4, K , and SO42- in a solution prepared by dissolving 2.11 × 10-4 g K2SO4 in 2.00 L of water. Express all three concentrations in molarity. Additionally, express the concentrations of the ionic species in parts per million (ppm). Note: Determine the formal concentration of SO42-. Ignore any reactions with water.

K2SO4= ?M
K+= ? M = ? ppm
SO4(2-)= ?M = ?ppm
