16. What is the ratio of the actual yield to the theoretical yield, multiplied by 100%
a. Mole ratio
b. Percent yield
c. Avogadro yield
d. Excess yield

B.

Explanation:

Actual/ “ideal” (100) x 100 = percent yield.

The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.
