After the second half-life of uranium, half of the original amount will remain. Therefore, if you start with 80 grams of uranium, after one half-life you would have 40 grams remaining, and after the second half-life, you would have 20 grams.
Uranium is not typically found in significant quantities in the Caribbean. The region does not have major uranium deposits, and if present, they would likely be limited and not commercially viable for mining.
To find the number of uranium atoms in 6.2 g of pure uranium, you would first determine the molar mass of uranium, which is approximately 238.03 g/mol. Next, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the grams of uranium to number of atoms. So, 6.2 g of uranium would equal approximately 6.2 x (6.022 x 10^23 / 238.03) uranium atoms.
To calculate the mass of uranium, we need to know the molar mass of uranium hexafluoride (UF6), which is approximately 352 g/mol. Given that the sample has 175.5 g of UF6, we can calculate the mass of uranium by multiplying the molar mass of uranium by the ratio of the molar mass of uranium to the molar mass of UF6 (238.03 g/mol / 352 g/mol) and then multiplying by the mass of UF6 provided. This would result in approximately 119.196 g of uranium in 175.5 g of UF6.
Uranium has a density of 19 grams/cubic centimeter. The difference between natural U and slightly enriched U is hardly worth considering. Work out the volume of the baseball from V = 4/3 x Pi x R3, R being half the diameter.
Roughly 8-10 tons of natural uranium ore are needed to produce one kilogram of enriched uranium, which typically contains 3-5% of the fissile isotope uranium-235. The enrichment process separates and concentrates the U-235 from the more abundant U-238 present in natural uranium.
Sounds like 42.2 grams, but I haven't checked your proportions, are these stoichometric?
To convert uranium atoms to grams, you need to know the molar mass of uranium. Uranium's molar mass is approximately 238.03 g/mol. Therefore, 7.5 x 10^21 uranium atoms would weigh approximately 0.625 grams.
The molar mass of uranium is approximately 238 grams per mole. Therefore, 0.500 mole of uranium would have a mass of 0.500 x 238 = 119 grams.
There are approximately 2.5 x 10^21 uranium atoms in 1 gram of uranium.

In a uranium ion, the number of electrons is determined by the ion's charge. Uranium typically loses 2 electrons to form a U2+ ion. Therefore, the second orbital of a uranium ion would contain 8 electrons in total.
It is estimated that about 1% of the mass of the sun is made up of heavy elements, which would include uranium. However, the exact amount of uranium present in the sun is difficult to determine due to the extreme conditions in its core.

Now liquid uranium has not applications.
A 7 gram uranium pellet can generate a significant amount of power through nuclear fission. The exact amount of power produced would depend on the specific isotopes of uranium present, as well as the efficiency of the nuclear reactor or device in which it is used.
