Question
The following procedure provides a crude method of determining the molar mass of a volatile liquid. A liquid of mass 0.0153 g is introduced into a syringe and the end is capped (sealed). The syringe is transferred to a temperature bath maintained at 58.5 oC, and the liquid vaporizes. As the liquid vaporizes the plunger is pushed out. At equilibrium, the plunger reads 5.76 mL of gas. Atmospheric pressure is 740. mmHg. What is the approximate molar mass of the compound (in g/mol)?

Calculate the volume of carbon dioxide adjusted to 25 °C and 1 atm, that plants need to make 1.00 g glucose, CóH12O6, by photosynthesis in the reaction 6CO2(g) + 6H20(I) C6H1206(s) + 602 (g).arrow_forward1.25 L container holds a stoichiometric mixture* of ethene (CaH4), ethane (CaH6) and oxygen at a total pressure of 1.55 atm and a temperature of 24.5 °C. The mixture is ignited and completely combusts to form carbon dioxide and water. The water is removed from the vessel, leaving only carbon dioxide at a total pressure of 0.926 am at the same conditions.

Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.arrow_forward
- Ether was one of the first anesthetics discovered. Assume that several mL of ether is placed in an Erlenmeyer flask with a volume of 293 mL, and the flask is immersed in water at 36.0 °C until the last drop of liquid disappears, leaving the flask filled with ether vapor. The flask is then removed from the water bath, and the weight of ether that condenses in the flask is measured. If 0.801 grams of ether collect in this experiment at a pressure of 104.3 KPa, what is the molecular weight of ether from the experiment? 1 molecule unknown substance = ________ amuarrow_forwardUse your text or other reference to find the partial pressure of water at 25°C, 26°C, and 27°C and record those values.arrow_forwardA volatile hydrocarbon (a binary compound of carbon and hydrogen) was determined to be 92.3 % carbon, by mass. In a separate experiment, utilizing the Dumas method, 4.00 mL pure liquid sample of this hydrocarbon is vaporized in an Erlenmeyer flask when the barometric pressure is 768.0 torr. The empty flask was fitted with a foil cap pierced with a pinhole and weighed 25.3478 g. After the excess gas escaped, the temperature was measured as 98.0 °C. The flask and contents were subsequently cooled to 25 °C and the vapor condensed into a liquid. The weight of the flask and contents is found to be 25.6803 g. The exact volume of the flask was determined to be 128.5 mL. Using this information, determine both the empirical and molecular formula of this hydrocarbon.
