Element X has two isotopes. If 98.90% of the element has an isotopic mass of 12.00 amu, and 1.10% of the element has an isotopic mass of 13.01 amu. Calculate the average atomic mass for this element and identify the element. Use a stylus, pencil (if using a chromebook), or finger to solve the problem in the space below. (1 point work, 1 point answer, 1 point sig figs, 1 point units, and 1 point for correct element identified)
