- What mass (g) of ethanol, CH3CH2OH(), can be vaporized at its boiling point of 78.4 C by transfer of 500. kJ to the liquid? The vapH of ethanol is 38.6 kJ/mol at this temperature.arrow_forwardA 1.40-g sample of polyethylene, a common plastic, is dissolved in enough organic solvent to give 100.0 mL of solution. What is the average molar mass of the polymer if the measured osmotic pressure of the solution is 1.86 mm Hg at 25 C?arrow_forwardThe molecular mass of butanol, C4H9OH, is 74.14; that of ethylene glycol, CH2(OH)CH2OH, is 62.08, yet their boiling points are 117.2 C and 174 C, respectively. Explain the reason for the difference.arrow_forward
- Seawater contains about 3.5% by mass dis- solved solids. As a rough approximation, assume that the dissolved solids are predominantly NaCl(aq) [that is, 3.5 grams of NaCl(aq) in 96.5 grams of H2O(l )] and estimate the normal boiling point of seawater.arrow_forwardBy how much is the vapor pressure of water lowered 2g of sucrose is added to 100g of water at 20 degrees celcius? (note that the vapor pressure of water at 20 degrees celcius is 17.5mmHg)arrow_forwardAutomotive antifreeze is a mixture of mostly ethylene glycol (C2H6 O2) and water. What mass percent of ethylene glycol is required to create a mixture with a boiling point of 221 °F?arrow_forward
- What is the respiration rate for a breath every 2.5 seconds? What solids are made up of large numbers of independent, constituent units, some of which attract and others repel.arrow_forwardRefer to Fig. 4A.8. Describe the phase or phases present as a sample of CO2 is heated steadily from 100 K: (a) at a constant pressure of 1 atm; (b) at a constant pressure of 70 atm.arrow_forward0.640g of Hexachlorophene (in soap) is dissolved in 25.0g of chloroform (Kb = 3.63 °C·kg/mol, Tb = 61.70 °C) and the boiling point of the solution is 61.93 °C. What is the molar mass of the hexachlorophene? It is not ionic.arrow_forward

But if a 200. g sample of X is prepared with 7.38 g of urea (NH2)2CO dissolved in it, the sample is found to have a condensation point of 111.9 C instead. Calculate the molal boiling point elevation constant Kb of X.arrow_forwardIn a case where pressure drops below triple point, explain what will happen to the phase transition of solid waterarrow_forward
