I've had mollies off and on through my life and have had them in heavily planted and lightly planted tanks.
The fry will do much better with a heavily planted tank since there's so many places for them to hide out. I've found that usually out of a "litter" I'll have either a small amount survive (2-3) or a large amount (10+) it totally depends on the fry and if they're "smart" enough to hide.
For survival it's if it fits in a fish mouth, it'll be swallowed by the fish mouth
I've found though usually 3-4 weeks the younglings will start getting brave and coming out
Mollies are like guppies in respect to breeding, they are live bearers and will have the male chasing the female as soon as she's done giving birth, watch them they will square out when they get close (the female) and may (depending on the darkness of the particular fish) show a gravid (dark) spot prior to giving birth.
They're very cool fish and if taken care of can easily live for a few years (I had a few make it to 4 when I was younger) and they are pretty easy to get along with as for parameters.
Hope that helped
