3.011×10 Atoms of an element weight 1.15gm the atomic mass of an element is

atomic mass of an element = mass of 1 mole of that element.
wt of 3.011 x 10^10 atoms = 1.15 g
therefore wt of 1 atom = (1.15)/(3.011 x 10^10)
therefore wt of 1 mole of atoms = (1.15)/( 3,011 x 10^10) x 6.022 x 10^23
= 2.3 x 10^13 g/mol
note the answer is not possible so therefore the question must be wrong. Please check the number of atoms .The procedure remains the same.)
