When nuclear fission occurs, some mass is lost. where does the mass go?

The situation when nuclear fission occurs, some mass is lost is also called the mass defect and as a result  the matter turns into energy. If you want to know where the mass does go  Albert Einstein will be your helping hand :  E = mc^2. Using this formulae you will solve the task and find out the  direction of mass.
