How do you know which isotope is abundant
WebYou must find the total mass (500 + 1200 = 1700) and divide it by the total number of people (30) so the average is 56.67. Notice the average is closer to the mass that had more people. You could do the same thing using … WebJun 7, 2024 · 1) You need to use the atomic mass of copper. You can find it in a periodic table. It is 63.546 amu. 2) The atomic mass is the weigthed mass of the different isotopes. This is, the atomic mass of one element is the atomic mass of each isotope times its corresponding abundance: => atomic mass of the element = abundance isotope 1 * …

WebIsotope 1 has a mass of 120.9038 amu and a relative abundance of 57.4 %, and isotope 2 has a mass of 122.9042 amu and a relative abundance of 42.6 %. (a) Find the atomic mass of this element. (b) By com. There are two naturally occurring isotopes of europium: Eu-151 (151.0 amu) and Eu-153 (153.0 amu). WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one.
