بیشتر6. We can see from figure 16.9 that the molar solubility at 20°C for oxygen and methane are 1.4 mM and 1.5 mM, respectively. As temperature increases, the solubility of the gases decreases, causing gases to bubble out of solution. The concentration of oxygen will decrease from 1.4 to 1.0 mM, while the concentration of methane will decrease from

بیشترExplanation: Mass of KI = 500mL soln × 1 L soln 1000mL soln × 0.15mol KI 1L soln × 166.0 g KI 1mol KI = 12 g KI.
