Determine the mean molecular mass of a star for both the scenario of being completely neutral and the scenario of completely ionised if its composition is X = 0.734, Y = 0.250, Z = 0.016.
Added by Selena F.
Step 1
First, we need to determine the atomic mass of each element in the star's composition. We can use the periodic table to find the atomic masses: - Atomic mass of hydrogen (H): 1.008 - Atomic mass of helium (He): 4.003 - Atomic mass of all other elements (Z): we Show more…

Consider an element Z that has two naturally occurring isotopes with the following percent abundances: the isotope with a mass number of 19.0 is 55.0% abundant; the isotope with a mass number of 21.0 is 45.0% abundant. What is the average atomic mass for element Z? Average atomic mass of Z = [mass]
