Question

Calculate the mass defect (in g/mol) of an atom of Li-7, given:

Mass of Li-7 atom: 7.016004548 (g/mol)
Mass of electron: 0.0005486 g/mol
Mass of proton: 1.007276 g/mol
Mass of neutron: 1.008665 g/mol

Give your answer to five decimal places.

Calculate the mass defect (in g/mos) of an atom of Li-xt given i Mass of Linz atom & T 016004548 (9lmas) Mars of electron = 0.00054 86 (g/mol) Mass of profon t l. 007276 (g/mol) Mans of Neutron = 1.008665 (9/may) Daro the mone defect can be calculated by using the following equation Am = [2 (mpt me ) + (A-2) mn] - matom Where Am = mass detect (g/mol) and 2 = atomic number mp = mass of profon me= mass of electron A = mass number mn = marss of neutron, Matom & mass of nuclides And here Z=3. mp = 1.007276 g/mol me=0.ooos 486 g/mol A = 7 mn= 1.00 8665 g/mol Matom = 701604548
