Tavery, some of the above posts have been a little abrupt, which is a pity, as this makes it harder for you to seek advice. The reason for their strong reaction is that your poor molly has ended up in a very bad situation; I am surprised that the
shop did not warn your husband about his purchase.
Basically, mollies are tropical freshwater fish. They can not be kept in a fishbowl (nor should goldfish for that matter). They require heated water, proper filtration and plenty of room to move (15 gallons, I'd say). The water must be dechlorinated and regular small water changes (20% a week or so) should be performed. You should never change all the water at once, unless you have some absolutely lethal parasite in there.
To keep a molly a fishbowl is a little like buying a large dog and then locking it up permanently in the cupboard under the stairs. No doubt the poor thing aborted her fry due to stress.
Assuming the mother is still alive, you now need to decide what you are going to do with her. It is going to be a choice between getting her a better tank or taking her back to the shop. Left in the fishbowl she will die a very unpleasant death (basically stewing in her own waste). You should also to complain to the manager, if your husband has been wrongly advised (ask him how the transaction happened).
Then you will want to decide what to do with the fishbowl. Do NOT get a godlfish for it. Goldfish are heavier waste producers than mollies and need even more space.
That tank would make an acceptable home for a betta, aka Siamese fighting fish. If you want to use it, go on the betta forum and ask about setting it up for a betta.

Do you mean to imply that one should do less research when setting a child up with a pet? More, I would have thought. To your responsibilities for the fish are added your responsibility of teaching the child and making her pet experience enjoyable.
