Title: A hypothetical element, Rz, has two isotopes: 169Rz = 168.94 amu and 171Rz = 170 Post by: xlr300 on Dec 11, 2014 A hypothetical element, Rz, has two isotopes: 169Rz = 168.94 amu and 171Rz = 170.98 amu. Eleven of every fifteen atoms of Rz found in nature exist as the 169Rz isotope. What is the average atomic mass of the element Rz?
A) 169.48 amu B) 168.95 amu C) 170.56 amu D) 171.01 amu Title: Re: A hypothetical element, Rz, has two isotopes: 169Rz = 168.94 amu and 171Rz = 170 Post by: dustyparticle on Dec 18, 2014 Content hidden
