- Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.Given the following solubility curves, answer the following questions: (a) In which of the two compounds can more solute be dissolved in the same amount of water when the temperature is decreased? (b) At what temperature is the solubility of both compounds the same? (c) Will an increase in temperature always increase solubility of a compound? Explain.chemist prepares a solution of conper(li) sultate (USO,] by DIYmea suning out 092 g of copper(I) culfate into a 300 mE volumetric flask and filling the flask to the mark with water.
