Critical point coordinates for ethanol (46.068 g mol', d= 0.79 g ml) is 514 K and 62.18 atm, and normal boiling point is 78.4 °C. 4.56 ml ethanol is put to a container with a volume of 4.82 L and waited for equilibriate. What is percent of the remaining liquid ethanol in the container by mass compared to initial total amount at 20°C? Enter only number with two decimal digits without percent (26) sign, ie. 12.3456% should be entered as 12.35 Answer:

A student performed the experiment described in this module, using 7.00 mL of a 1.8% H₂O₂ solution with a density of 1.01 g ml-1. The water temperature was 20 ° C, and the barometric pressure in the laboratory was 30.02 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 45.1 mL of O2. (6) Calculate the mass of the H2O2 solution.

Clare extracted GONG, an essential oil. Clare utilized steam distillation to extract GONG from the plant's leaves. Clare discovered that the mixture boils at 98.5 degrees Celsius, with the vapor pressures of GONG and water being 5.06625 kPa and 725 mm Hg, respectively. Dee discovered that the distillation yielded 0.7249 mL of GONG and 1.2378 g of water. According to data, GONG has a density of 0.9789 g/mL. Determine GONG's molecular weight (in grams per mole).

A piece of metal weighing 0.713 g was placed in an eudiometer containing aqueous HCI. After the metal fully dissolved ,23.5 mL of hydrogen gas was collected by displacement of water and a 400 mm column of water was observed. The water temperature was 25 degrees Celcius and the barometric pressure was 758.8 mm Hg ( torr). Refer to the introduction and data sheet to solve the following problems.What is the vapor pressure of the water vapor in the column? What is the pressure of the water column expressed in mm Hg (torr) ? The density of mercury is 13.6 mL.
