Best idea is for her to probably apply for citizenship (if she hasn't already) while you try and sort out your divorce. If she applies as a citizen it doesn't matter (other than the preference category) if you are married or not and it will be faster to get the visa number.
Given that your ex is an American anyway, I doubt this is much of an issue because he won't be included on your application. If he's not included on the application USCIS doesn't know about him and given that you're getting divorced they don't need to, so basically your mom applies as if you had no husband.
Bear in mind this is not a quick process. It's hard to say how long because you have to look at trends in the visa bulletin and it's not clear what your category is, could be first, second (B) or third.

Don't look at the dates in the table and simply minus them off today's date and think that will be the date you get your visa. From year-to-year USCIS may process a couple of years worth of applications in a year, or they may only process six months worth of applications, so you have to go back and look through the bulletins and see if you can indentify trends.
But regardless, it will be several years before your petition is approved. By then you will be long since divorced.
