On earth, tin has 10 different stable isotopes. The heaviest, 124 Sn makes up 5.80% of naturally occurring tin atoms. a) How many atoms of 124 Sn are present in 42.7 g of a natural sample of tin? 124 Sn: 1.491e24 atoms Scientific Notation: 1.491 x 1024 Helpful tip: To enter a number in scientific notation, enter 0E5 or 1.0e5, for 1.0 x 105 where the E# (or e#) denotes 10# b) Considering 124 Sn has an isotopic mass of 123.905 amu, calculate the mass of this isotope in the sample. Mass: 6.0
