Question

Suppose you have 0.664 mol of an ideal gas in a 0.454 L container at 39.97 atm. a) What is the temperature of this gas? b) Sketch a pressure versus volume graph for this ideal gas, either using the graph paper on the next page or in a spreadsheet such as Excel. Have the graph go out to 4 L and 70 atm. Use at least 6 points to draw this curve. c) On the graph from part b, use a dotted line to sketch the approximate curve that you might expect to see for a real gas with strong repulsive intermolecular interactions at high pressures (i.e. above 10 atm).

Question 1.

Answer 1

Sot" - Number of moles of gas, n= 0.664 Volume of container, v=0.454 l. pressure of gas, P= 39.97 aton. so, temperature of the gas is, T = PVN where R is " MR) gas constant 39.97 x 0.454 on or 0-664 x 0.082057366 T = 333.046k T= 60.046°C
