The pressure exerted by the gas molecules on the surface of the liquid is referred as vapor pressure.Answer and Explanation: Vapor pressure is a colligative property of solutions which means that its value depends on the amount of the solute in the solution. The lowering of...Become a memb...
The vapor pressure of water at 20℃ is 2.338 kPa. If the solute in a solution made from 10.0 g of NaCl in 1.00 kg of water is 100% dissociated, what is the vapor pressure of the solution at 20℃? 相关知识点: 试题来源: 解析 解:$$ x _ { A } = \frac { \frac { 1 0 0 0...

Raoult's law(räo͞olzˈ)[for F. M.Raoult, a French physicist and chemist] states that the addition of solute to a liquid lessens the tendency for the liquid to become a solid or a gas, i.e., reduces the freezing point and thevapor pressure(seesolution). For example, the addit...
