Temperature (∘C) Solubility (g/100 g H2O) 20 11.0 30 23.0 You have prepared a saturated solution of X at 20∘C using 27.0 g of water. How much more solute can be dissolved if the temperature is increased to 30∘C? Express your answer with the appropriate units.
g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...
Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...
alex dissolves 1. Alex dissolves 19.8 g solute into 38.0 g water and finds that crystals first appear in the solution at temperature: 11.0 °C, calculate the solubility of the solute. 2. a. A mixture of 42.00 g water and 15.44 g of KNO, looks clear solution at 84 °C. As it cools down to 71°C, a few crystals start to appear. Will it be saturated or unsaturated solution at 62"C? b. A mixture of 30.00 g water and 18.45...
1f. At an unknown temperature a solution made of (7.740x10^0) g of a non-volatile solute dissolved in 100.0 g of water has a vapor pressure of (5.51x10^1) mm Hg. What is the vapor pressure of pure water (in mm Hg) at this unknown temperature? The molar mass of the solute is (5.360x10^1) g/mol. 1g. A solution is made of two volatile solutes: Chemical A (with a pure vapor pressure of 80.0 mm Hg) and Chemical B (with a pure vapor...
17) Methanol, CH3OH, is sometimes used as an antifreeze for the water in automobile windshield washer fluids. How many moles of methanol must be added to 6.50 kg of water to lower its freezing point to -13.0 ∘C? For each mole of solute, the freezing point of 1 kg of water is lowered 1.86 ∘C. 18.) The following table gives the solubility of solute X in water at two different temperatures: You have prepared a saturated solution of X at...
What is the unknown solute in a solution of benzophenone with using freezing point depression? In this lab, the test tube with the solution was put in a hot water bath on a hot plate. The test tube was in a beaker. Mass of benzophenone: 6.863 g Mass unknown: 0.752 g I placed benzophenone in a test tube in the hot water bath. Once it melted, I recorded 48.5 C. I stirred the test tube and the temperature lowered to...
