Problem 56328. Molar Air Density from Temperature and Pressure

The molar density of air can be found from the Temperature and Pressure using the ideal gas law.
where the Molar density STP :
from Avagadro's number:
and Loschmidt’s number STP:
And STP Temperature and Pressure:
Write a function that finds the density of air in moles per cubic centimeter for input temperature (in Kelvin) and pressure (in mb). This function should allow: a single input temperature and pressure pair, a single temperature and vector of pressures, a single pressure and and a vector of temperatures, a vector of pressures and a vector of temperatures of the same size (interpreted as pairs). Return -1 if a P and T are unequal vector dimensions greater than 1.
