Use the chart below to answer the following question: Isotope Mass (amu) Percent Abundance X-30 30 18.5% X-31 31 48.5% X-32 32 12.5% What is the average atomic mass for Element X

a. hope i'm right

explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
