Approx. 9.1024 atoms.
1 nanogram of natural uranium = 2,53.1012 atoms
Which compound
1. The natural abundance of 235U is 0,72 % (atomic percentage). 2. 4,99 g of natural uranium contain approx. 8,8396.1019 atoms of 235U.
The answer is 15,2.1021 atoms of uranium.
In a pure sample, one (uranium itself). In ores, traces of lead, thorium and rare earth elements are usually present.
One mole of a substance consists of 6.023 X 1023 number of atoms or molecules. So, 0.896 moles of uranium will have 5.396608 X 1023 atoms.
156,86.1020 atoms of uranium in 6,2 g uranium
113 662.1016 uranium-234 atoms
The answer is 0,1518.10e+23 atoms.
The uranium atom has seven electron shells.
7,5.1021 uranium atoms = 2,9644 grams
The answer is 6,31 moles Ag.
