Suppose a new chemical becomes a health concern when it is released as air pollution into the atmosphere. After analysis of the health effects, the EPA decides to create another CAP for this new chemical, and therefore it sets a NAAQS for it$.$ Here is some information:

The molecular weight of the new chemical is $43\mathrm{.}87$ kg$/$kmol

The air pressure of interest is $97\mathrm{.}8$ kPa

The air temperature of interest is $25\mathrm{.}79$oC

The NAAQS set by EPA for this new chemical is $62\mathrm{.}0$ mg$/$m$3$

At the given temperature and pressure of interest, calculate the mole fraction of this chemical at the given NAAQS. Give your answer in PPM$.$
