Question

Is significant figure important for atomic radius calculations?

Calculate the radius of a vanadium atom, given that V has BCC crystal structure, a density of 5.96g/cm³, and an atomic weight of 50.9g/mol

What if we solve this question with 33 significant figures and 55 significant figures? What will be different?

Answer 1

5 significant figures would not be correct since the most accurate measurement being used has only 3 significant figures.  Your answer should have 3 significant figures.
