  • What number is that after the (35.9671), where you put zeros in a bracket. Isn't it supposed to be (0.01)? wendy commented 11 months ago
  • when I went through it with my calculator, it gave me 31.8250 amu. How did you get the 32.9693 amu? wendy commented 11 months ago

  • Hey Wendy, that's suppose to be 0.0075 because in your table there, thats the abundance of the isotope with mass X. 0.75 is the abundance, but we need to use natural abundance, so 0.75/100 = 0.0075 Dasha commented 11 months ago
  • I meant to say we need fractional abundance, sorry. Also, the last number in the parenthesis is 0.0001, because again we divided 0.01 by 100 Dasha commented 11 months ago
  • Yes, thank you. but my question is, I calculated all of the numbers and it gave me 31.8250 instaed of the 32.9693. wendy commented 11 months ago
  • Which answer is right. The 32.9693 or the 31.8250. wendy commented 11 months ago
  • Which answer is right. The 32.9693 or the 31.8250. wendy commented 11 months ago
  • I got an answer of 32.97 amu Dasha commented 11 months ago
  • Did you do something on the given atomic mass 32. 0648? wendy commented 11 months ago

FORMULA OF ISOTOPE

  • THIS IS THE FORMULA wendy commented 11 months ago

Hey Wendy! No I did not do anything to the mass of the element. Maybe this will make it a little clearer to see.
