6. Suppose you identify a new element, Pivotium. Pivotium has two isotopes: Pivotium-425 and Pivotium-416. In the mixture, 28% of the mixture is Pivotium-425; the rest of the mixture is Pivotium-416. What is the relative atomic mass for Pivotium? amu Submit Answer unlimited submissions remaining Score: 0/2 7. Last one, but this time, let's try THREE isotopes. Suppose you identify a new element, Interactium. Interactium has three isotopes: Interactium-285, Interactium-287, and Interactium-293. In the mixture, 28% of the mixture is Interactium-285, 32% is Interactium-287, and the rest of the mixture is Interactium-293. What is the relative atomic mass for Interactium? amu 6.
