Answer:
195.199grams
Explanation:
Fluorine has a molar mass of 18.99984 while calcium has a molar mass of calcium is 40.08.
1 mole of calcium fluoride has a mass of 40.08+2×18.99984
=78.0797 grams
if one mole has a mass of 78.0797 grams, then 2.5 moles have:
2.5 moles× 78.0797 grams/mole= 195.1992 grams
First, find the number of moles of UF6
Avagadro's number = 6.023 x 10^23
Number of moles = 8.0 x 10^26 / Avagadro's number = 8.0 x 10^26 / 6.023 x 10^23 = 1.328 x 10³ moles
Molecular weight of UF6 = Molecular weight of U (238.02891) + Molecular weight of F6 (6 x 18.9984032) = 238.02891 + 113.9904192 = 352.0193292 g/mol
Therefore mass of 8.0 x 10^26 UF6 molecules = 352.0193292 g/mol x 1.328 x 10³ moles = 467.481669 x 10³ grams

Energy, kinetic, potential
She's 32. She can vote. She is entitled to privacy and it would take almost an act of Nature to disclose what she has asked of her doctor.
HIPAA has to do with who can look at medical records. If she doesn't want her husband to see those records, they are locked tighter than a safe on Wall Street.
From what I've read, that ruling has many implications. He is her next of kin. Can he sue if something goes wrong? There are more questions here than answers. Will the records be opened if something does go wrong? Where does freedom from prying eyes end and the good of the commonwealth begin?
If this question is anything but a school question (I'm assuming that is all it is), and somebody needs to act on the answer, for goodness sake consult someone who really knows and is governed by HIPAA. This is nothing to fool around with.
