Lighter elements are converted to the higher elements. They fuse together to become one big nucleus. Just as two small drops can fuse to become a bigger one.
Moles of Uranium = 7.6x10^21/6.02x10^23 = 0.012 moles.
Mass of Uranium = moles x atomic mass of Uranium
= 0.012 x 238.029
= 2.85 grams.
Hope this helps!
