Great job, however, there is one error in your calculation, namely the assumed mass of the Empire State Building as 365,000 tons. The 'ton' used here is an American 'short ton', that equals 2,000 pounds (907.18474 kg) and not 1,000 kg (which would be a 'metric ton', or 'tonne')

So the real mass of the ESB is 331,122,430 kg = 331,122 metric tons.

This changes the mass of the Daily Bugle to 1,163,460,791.7 kg, the potential energy that Spider-Man took to 5.1684687926 tons of TNT, and his lifting strength to 581,730 metric tons.
