(4 Points) An element is made up of three isotopes, one of which (sºx has a % abundance of 3.09%, while the other two are unknown. If the mass of the three isotopes are 28x(mass = 27.9769), 29x(mass = 28.9765) and
30X(mass = 29.9738), and the atomic weight of the element is 28.0855 amu, what are the % abundances of
the other two isotopes?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
