N-13 undergoes positron decay. What is the product nucleus? Enter your answer using the same format, i.e, symbol-mass number Student Response Value Correct Answer 1. C-13 100% Equals C-13 (100%) Score: 1/1 2. An atom of 110 I has a mass of 109.935060 amu. Calculate the mass defect (deficit) in amu/atom. Use the masses: mass of 1 H atom = 1.007825 amu mass of a neutron = 1.008665 amu 1 amu = 931.5 MeV Give your answer to 4 significant figures and DO NOT use E notation. No charity points will be awarded. ...... Student Response Value Correct Answer 1. .9736 100% Equals 0.9735 (100%) Equals 0.9736 (100%) Equals .9735 (100%) Equals .9736 (100%) Score: 1/1 3.
