1997 Jeep Wrangler Using a lot of Coolant Please help

I just recently bought a 1997 jeep wrangler in really good shape and with low miles. I had been driving it for about 2 weeks and realized that it had been using a lot of coolant. I thought I found out the problem with my radiator when I found a leak. So I replaced my radiator and I recently looked again at my coolant and it is still using quite a bit of coolant. Please help so I can get this fixed before I go back to school.
