This means that the mole fraction of water will be Pure water has a density of 1g/cm 3 or 1000kg/m 3. The density of pure water:-The density is defined as the mass per unit volume ratio. At 20 degrees Celsius it is 998.23 kg/m3 ( or 0.99823 g/cm3). Water has a density of 997 kg/m 3 at 25 degrees Celsius. It is exactly 1000 kg/m3 at 4 degrees Celsius. But you’re right that it does vary a little bit with temperature. The total number of moles present in the solution will be Use glucose and water's respective molar masses to determine how many moles of each you have This means that all you have to do is determine the mole fraction of water in the solution.Īs you know, mole fraction is defined as the number of moles of a component of a solution divided by the total number of moles present in that solution. What is the density of water at 24 degrees Celsius Fresh water has a maximum density at around 4° Celsius.Density of Water (g/cm3) at Temperatures from 0☌ (liquid state) to 30.9☌ by 0.1☌ inc. In your case, you know that the vapor pressure of pure water at is equal to #23.8# torr. 0.9982 g/mL UKAS ISO/IEC17025 and ISO Guide 34 certified, density: 0.9982 g/mL at 20 ☌, density: 0.9970 g/mL at 25 ☌. ![]() is the vapor pressure of the pure solvent.There are three 'answers' you would get: One molar volume for the liquid phase. Then, press enter until your answer converges. Given that the partial molar volume of water in this solution is 16. #chi_"solvent"# is the mole fraction of the solvent Thus, put the following into your TI calculator to solve for ¯¯ ¯V at 25C, or 298.15 K: (X X3 24.82017175X2 + 5.536X 0.16879264 3X2 49.6403435X +5.536) X. At 25 degrees Celsius, the density of a propanol-water (C3H7OH in H2O) solution which is 30 by mass propanol is 1.05 g/cm3. ![]()
