Answer the following questions about the radiochemistry involved in PET scans. All answers are numerical. (Hint: 1 mCi is exactly 3.7 x 107 Bq. ) a) Fluorine-18 can be synthesized by smashing tritium (3.01605 amu) into 16O (15.99491 amu), which results in the formation of 18F (18.00094 amu) and a neutron (1.00866 amu) according to the this reaction: 3H + 16O → 18F + n How much energy is emitted per mole in this reaction? ________x 10¹¹ J/mol b) If the initial dose of 18F (t1/2 = 109.8 min) received by the patient is 12.00 milliCurie (mCi), what is the disintegration rate (in mCi) in the patient's body at exactly 24 hours after they receive that initial dose? ________x 10-⁹ mCi need both parts or else I will downvote
Answer the following questions about the radiochemistry involved in PET scans. All answers are numerical. (Hint: 1 mCi is exactly 3.7 x 107 Bq. )
a) Fluorine-18 can be synthesized by smashing tritium (3.01605 amu) into 16O (15.99491 amu), which results in the formation of 18F (18.00094 amu) and a neutron (1.00866 amu) according to the this reaction: 3H + 16O → 18F + n
How much energy is emitted per mole in this reaction? ________x 10¹¹ J/mol
b) If the initial dose of 18F (t1/2 = 109.8 min) received by the patient is 12.00 milliCurie (mCi), what is the disintegration rate (in mCi) in the patient's body at exactly 24 hours after they receive that initial dose? ________x 10-⁹ mCi
