Question

What is the mass, in grams, of a sample of 6.12 × 10^24 atoms of manganese (Mn)? Show your work or explain the steps that you used to determine your answer.

Answer 1

Atomic mass of Manganese ( Mn ) = 54.93 u.m.a

54.93 g ---------------- 6.02x10²³ atoms
?? g -------------------6.12x10²⁴ atoms

( 6.12x10²⁴) x 54.93 / 6.02x10²³ =

558.42 g of Mn

hope this helps!
