The solubilities of three salts in water are shown in the graph.For each salt, determine how much will remain undissolved if 500 g is mixed into a liter of pure water at 40°C. One significant figure is sufficient in each answer.- Pb(NO₃)₂: ____ g- KCl: ____ g- K₂Cr₂O₇: ____ g**Graph Description:**The graph displays the solubility of three salts—Pb(NO₃)₂, KCl, and K₂Cr₂O₇—in water as a function of temperature, ranging from 0°C to 100°C. The solubility is measured in grams per liter (g/L).1. **Pb(NO₃)₂ (Lead Nitrate):** Represented by a blue line, the solubility of Pb(NO₃)₂ increases steadily with temperature. At 40°C, its solubility is approximately 700 g/L.2. **KCl (Potassium Chloride):** Represented by a green line, KCl shows a moderate increase in solubility with temperature. At 40°C, its solubility is about 400 g/L.3. **K₂Cr₂O₇ (Potassium Dichromate):** Represented by a red line, the solubility of K₂Cr₂O₇ increases noticeably with temperature. At 40°C, its solubility is around 150 g/L.

500 gm of each salt is mixed with 1 L water at 40 degree Celsius.

A researcher prepares 100 mL of aqueous solution containing 0.1 g of a protein. The researcher then uses an experimental apparatus ,where he notes that, at room temperature (300K) and atmospheric pressure (101.325 kPa), distilled water flows naturally into the solution compartment. However, when he applies an extra pressure of 1000 Pa he observes that the flow of distilled water ceases and the system is in balance. Calculate the molar mass of this protein, in kDa (1 Da = 1 g/ mol); Why does the flow of distilled water cease with the application of the pressure of 1000 Pa? Explain in terms of potential chemicals. %3D
