What is the isotopic atomic mass of an isotope if 9.7023 × 10²² atoms weighs 4.0256 g? A)0.64858 g B)24.305 g C)24.986 g D)13.728 g E)4.0256 g

Question

Quizplus · Accepted Answer

The calculation can be done using the formula:
isotopic atomic mass = (total mass of atoms) / (total number of atoms)
isotopic atomic mass = (4.0256 g) / (9.7023 × 10^21 atoms)
isotopic atomic mass = 24.986 g. 
Therefore, the correct answer is C.
