Can I file the I-1485 for my mother who is already in the country and almost exhaust per 180 days maximum stay per entry on her 2yrs multiple entry v

Your mother can do an adjustment of status application through you (I 130/I-485) as long as you are a US citizen over the age of 21 and she is not barred under any of the inadmissibility grounds of the immigration laws. Your mother's almost exhausting or even exhausting the six months that she is given upon entry would not be a factor as she qualifies under the category of immediate relatives of US citizens if you are a US citizen and overstays are excused in such filings.
