Concept explainers
Interpretation:
Pressure in each container before and after the stopcock is opened has to be calculated. Also, the container after the stopwatch is opened has to be drawn.
Concept Introduction:
The properties that are dependent upon the size or the amount of eth matter contained in the system are termed as extensive properties. They are additive in nature.
Any gas obeys the assumption laid down in kinetic molecular theory is said to be an ideal gas. The combination of all the

Answer to Problem 6.92QE
Pressure in the left and right container before the stopcock is opened are
Explanation of Solution
Since each dot represents
Similarly, since there are four blue molecules that represent
The formula to convert degree Celsius to kelvin is as follows:
Here,
Substitute
Rearrange equation (1) to obtain the expression of temperature as follows:
Substitute
Substitute
After the stopcock is opened the volume is taken as the sum of the volume of both containers as it is an extensive property. Thus the total volume is calculated as follows:
Here,
Substitute
Similarly, the amount of substance or the number of moles is also an additive property, therefore, the total number of moles
Here,
Substitute
Substitute
Since when the stop corks are opened the number of moles must be equilibrated as the volume is equal on both sides. As a result, one molecule from the left container moves to the right so that each side has

- If equal masses of O2 and N2 are placed in separate containers of equal volume at the same temperature, which of the following statements is true? If false, explain why it is false. (a) The pressure in the flask containing N2 is greater than that in the flask containing O2. (b) There are more molecules in the flask containing O2 than in the flask containing N2.arrow_forwardConsider the following sketch. Each square in bulb A represents a mole of atoms X. Each circle in bulb B represents a mole of atoms Y. The bulbs have the same volume, and the temperature is kept constant. When the valve is opened, atoms of X react with atoms of Y according to the following equation: 2X(g)+Y(g)X2Y(g)The gaseous product is represented as and each represents one mole of product. (a) IfP A=2.0 atm, what is P8 before the valve is opened and the reaction is allowed to occur? What is P A+P B? (b) Redraw the sketch to represent what happens after the valve is opened. (c) What is PA? What is PB? What is P A+P B? Compare your answer with the answer in part (a).arrow_forwardA collapsed balloon is filled with He to a volume of 12.5 L at a pressure of 1.00 atm. Oxygen, O2, is then added so that the final volume of the balloon is 26 L with a total pressure of 1.00 atm. The temperature, which remains constant throughout, is 21.5 C. (a) What mass of He does the balloon contain? (b) What is the final partial pressure of He in the balloon? (c) What is the partial pressure of O2 in the balloon? (d) What is the mole fraction of each gas?arrow_forward
- You have a 550.-mL tank of gas with a pressure of 1.56 atm at 24 C. You thought the gas was pure carbon monoxide gas, CO, but you later found it was contaminated by small quantities of gaseous CO2 and O2. Analysis shows that the tank pressure is 1.34 atm (at 24 C) if the CO2 is removed. Another experiment shows that 0.0870 g of O2 can be removed chemically. What are the masses of CO and CO2 in the tank, and what is the partial pressure of each of the three gases at 25 C?arrow_forwardA halothane-oxygen mixture (C2HBrCIF3 + O2) can be used as an anesthetic. A tank containing such a mixture has the following partial pressures: P (halothane) = 170 mm Hg and P (O2) = 570 mm Hg. (a) What is the ratio of the number of moles of halothane to the number of moles of O2? (b) If the tank contains 160 g of O2, what mass of C2HBrCIF3 is present?arrow_forward
