The concentration of a gas is related to its pressure by the ideal gas law:

where n is the number of moles, V is volume (L), P is pressure (bar), and T is temperature (K).
(a) The maximum pressure of ozone in the Antarctic stratosphere in Figure 1-1 is 19 mPa. Convert this pressure into bars.
(b) Find the molar concentration of ozone in part (a) if the temperature is - 70°C.
