Question

How many atoms of

234U are there in 1 kg of natural uranium?​

Answer 1

this is actually chemistry.

1 mol contains 234 grams.

so 1kg contain 1000/234moles i.e 4.25 moles

1mol contain 6.023*10^23 atoms.

so 4.25 moles contain 4.25*6.023*10^23 atoms.

so the answer is 2.56*10^24 atoms.
