WHAT IS THE EFFEKT OF ADD K2CO3 TO ( METHANOL OG WATER)?
I add pure water (at 25 degrees C) and K2CO3 to a flask, then stopper the flask. I fasten this flask onto a stirrer, turn the stirrer on, and watch the flask and stirrer continuously for several hours. At the end of this time, there is still solid material left at the bottom of the flask. This happens even though: I) the stirrer does not stop or change speed; II) the flask is not removed from the stirrer; III) nothing...
A solution of methanol is prepared by dissolving 34.1 mL of methanol in sufficient water to give a total volume of 103.4 mL. What is the percent-by-volume concentration of methanol?
Methanol Water
The Boiling Point Diagram of Methanol-Water (Figure 5.6) shows Mole Fraction of Water versus Temperature, °C. Using the following atomic weights and the density of methanol of 0.792 g/ml, a 41.5 % v/v methanol in water solution (41.5 ml methanol and 58.5 ml water) is what mole fraction of water? Round to 2 decimal points with no units. Remember that the density of water is defined in the metric system as 1. (C = 12, H = 1, N =...
4. An aqueous solution of K2CO3 is prepared dissolving 53 kg of K2CO3 in 100kg of water at 293K. Calculate the molarity, normality and molality of solution. Density of the solution is 1.3g/ml (5)
A solution is made using 200.0 mL of methanol (density 0.792 g/mL) and 301.1 mL of water (density 1.000 g/mL). What is the mass percent of the methanol?
A solution of methanol and water has a vapour pressure of 213 Torr. What would you predict as the mole fractions of each component, assuming ideal behaviour? The vapour pressures of methanol and water are 256 Torr and 55.3 Torr, respectively. A) Xmethanol = 0.214, Xwater = 0.786 B) Xmethanol = 0.786, Xwater=0.214 C) Xmethanol = 0.900, Xwater = 0.100 D) Xmethanol = 0.885, Xwater=0.115 E) Xmethanol = 0.115, Xwater=0.885
