    A tank of volume 0.5 m^3 contains oxygen at a pressure of 1.5E6 Pa and a temperature of 20 C. Assume that the oxygen behaves like an ideal gas.

    a. How many kilomoles of oxygen are in the tank?
    b. How many kilograms?
    c. Find the pressure if the temperature i increased to 500 C.
    d. At a temperature of 20 C, how many kilomoles can be withdrawn from
    the tank before the pressure falls to 10% of the original pressure?

    Solution Summary

    In this exercise, the volume, the pressure, and the temperature of an ideal gas are given. Students are asked to find the moles and mass of gas in the given volume. Students are also asked to find the new pressure if temperature is changed. Lastly, when the pressure drops, students are asked to find the new number of moles of the ideal gas.
