What is the atomic mass number of 28.09?
The atomic mass number of an element is the sum of the number of protons and neutrons in its nucleus. To get the atomic mass number of 28.09, it typically corresponds to the average atomic mass of an element on the periodic table. For example, the element silicon has an average atomic mass of approximately 28.09, indicating that a silicon atom has an atomic mass number of around 28.

Calculate the atomic mass of element X if there are two isotopes of this element (X-24 and X-28) and 75 of all X atoms are X-28 isotopes.?
To calculate the atomic mass of element X, we can use the weighted average formula based on the isotopic abundances. Given that 75% of the isotopes are X-28 and 25% are X-24, the calculation is as follows: Atomic mass = (0.75 * 28) + (0.25 * 24) = 21 + 6 = 27. Thus, the atomic mass of element X is 27 atomic mass units (amu).
