Well..... There is no Boeing 744. But you may mean the Boeing 747-400 which is sometimes listed as a B744. Your question appears to be how many rows of seats there are in economy class. That depends on the load configuration, possible covid restrictions, and other factors. Your best bet may be to contact the carrier (airline) with which you intend to book your flight.
