While traveling to a distant universe, you discover the hypothetical element. You obtain a representative sample of the element and discover that it is made up of two Isotopes, X-23 and X-25. To help your science tear calculate the atomic mass of the substance, you send the following drawing of your sample with your report. In the report, you
also inform the science team that the light atoms are X-23, which have an isotopic mass of 23.02amu, and the dark atoms areX-25, which have an isotopic mass of 25.147amu.
What is the atomic mass of element X
