i don't even have a clue. i never took chemistry so i don't know. my head hurts just looking at that question

Answer 4

lololololol

Answer 5

sorry i couldn't help you

Answer 6

its okay bro thanks alot

Answer 7

no prob. good luck with your question

Answer 8

@princestonA hey,

for each isotope do the following.
Step#1 write down the atomic mass for one of the isotopes.
Step#2 convert the % abundance to decimal by putting the number over 100
Step#3 multiply the two numbers you'll get a number. just write this down and put a box over it to remember it.

do this for each isotope and then add the numbers up to get the total average mass.

Start with the first isotope they give you and tell me what you get.

Answer 9

This looks complicated but once you get it it's not that bad.

Answer 10

Oh thanks alot is 28.09

Answer 11

@Photon336 can you you do me one favor calculate the average atomic mass of rubidium. Rubidium has two isotopes, 85Rb and 87Rb. 85Rb has an atomic mass of 84.912 amu and occurs at an abundance of 72.17%. 87Rb has an atomic mass of 86.909 amu and occurs at an abundance of 27.83%. I wanna see the work so i know how to do it.

Answer 12

Yeah sure
