Calculate the VP of solution of 9g of glucose in162g of h2o at 293k |
|
Answer» The vapor pressure of the solution will be 17.45 mm of Hg Explanation : Given, weight of water = 162 g => NUMBER of moles of water, n₁ = 162/18 = 19 => number of moles of glucose, n₂ = 9/180 = 1/20 we know that vapor pressure of pure water at 293 k, P⁰ = 17.5 mm of Hg From RAOULT's law, (P⁰-P)/P⁰ = n₂/n₁ => 1 - P/P⁰ = 1/(20x19) => P/P⁰ = 379/380 = 0.99 => P = 17.5 x 0.99 = 17.45 mm of Hg Hence the vapor pressure of the solution will be 17.45 mm of Hg Read more on Brainly.in - brainly.in/question/15077548#readmore |
