- A 175 mL sample of neon had its pressure changed from 75 kPa to 150 kPa. Calculate the new volume. Answer: Unit:naining Time: 43 minutes, 12 seconds. estion Completion Status: QUESTION 20 In the experiment "Molar mass of volatile liquid", the pressure of the gas inside a flask was the same as atmosphere, and the temperature was identical to the boiling water temperature of water bath. How did you measure the volume of the gas inside the flask? - O Read the volume written on the flask. Fill the flask up to the brim with water and then transfer the water to a graduated cylinder. Measure the volume of the liquid added to the flask before heating the sample. Measure the volume of the liquid that condenses in the flask after cooling the sample.

Procedure(part A) 1) Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 2) Student B used the measurement of Flask no. 1 to be 250mL, without measuring the volume directed. 3) Student C recorded the temperature in degrees Celcius and used these values in calculations. Procedure(part B) 4) Water remained on the outside of the flask and on the foil when the final mass was determined.
- The gas in an engine cylinder is compressed until it has a volume of 0.045 liter and an absolute pressure of 28 atmospheres. If the engine cylinder contains 0.020 mole of gas, what is its temperature? Do not give handwriting solution.my topic is "Hazard placards on compressed gases For this assignment, you will be working in a small group to research the scenario indicated in the title of your group and explain how it is dependent on the properties of gases that you learned about in this module. You will compile your research in a short wiki page. The expectations for your group are as follows: • Each group member will research and contribute one source related to the application of gaseous properties to your assigned topic.Give only typing answer with explanation and conclusion 4. A chunk of dry ice, CO2(s), weighing 3.5 g is sealed inside a 2.0 L soda bottle initially containing 1.0 bar of air. What is the total pressure in the bottle after the dry ice sublimes and comes to 298.15 K? Enter the value with the appropriate number of significant figures. ⓘ bar
- Please see question 28, just the top one. I figure in this system the pressure is changing and my answer is the original pressure divided by the final pressure is equal to X. Do I have this correct? pv= nRT N and T and R are constants thus P1V1 = P2V2.g Cu ghificant digits. Do not include units! A 1.00 L sample of cooking gas taken from a cylinder was collected. Its mass, measured at 27.0° C and 100 kPa, was 1.768 g. Calculate the molar mass of the cooking gas in g/mol. Express your answer with three significant digits. Do not include units! g/mol A sample solution has a concentration of 12.4% by mass. What mass of solute (in g) is present in 50.0 g of this sample solution? DEIRA II ProcteUse Boyle's law, P1V1 = P2V2, to calculate the volume, in mL, of the dry H2 at room pressure. Please enter your volumes using three decimal places and do not use scientific notation. partial pressure of the dry H2 in Torr = 734.7 torr moles of magnesium and moles of hydrogen gas produced in each trial - trial 1 - 0.003188 trial 2 - 0.003225 trial 3 - 0.003163

Keep the first four digits from the scientific notation coefficient ( ?.??? *10x) and write it it standard notation with all zeroes, adding commas in the appropriate locations.There are 1.07 X 10-3 moles of gas molecules contained in a CO2 cartridge under 5.0-atm of internal pressure. After several uses, the internal pressure is 3.4-atm. How many moles of gas remain in the cartridge? How much gas will remain in the cartridge when the internal pressure equilibrates to standard pressure? (Assume that the temperature and volume remain constant.)Compressed gases are typically contained in cylinder-shaped containers instead of any other shape, both in portable and in bulk forms. Why? Explain your answer within the context of chemical safety.
