1. (a) A student is diluting a stock solution of a Vitamin C solution. The concentration of the stock solution is 3.687X10 M. 4.00 ml of the stock solution was transferred into a 50 mL volumetric flask and diluted to the mark with water. What is the final concentration of the dilute Vitamin C solution? (Refer to page 70 in the lab manual). (b) Would a solution prepared the same way but with 2.00 mL of the stock solution have...

II Revi Part A The vapor pressure of a substance describes how readily molecules at the surface of the substance enter the gaseous phase. At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level...

"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
