(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?

answer: c.

explanation:

the dependant variable is spilled water

the independent is the heat

gold is my favorite solid.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
