1. Radioactive decay of 40K atoms in an igneous rock has resulted in a ratio of 25 percent 40K atoms to 75 percent 40Ar and 40Ca atoms. How many years old is this rock?

1/2 of the original parent has decayed, thus one half- life has passed, and the rock is 1.3 billion = 1300 million years old
How many neutrons are in an atom of sulfur with a mass number of 35?a. 16 b. 17 c. 18 d. 19
Answers
As the mass difference between protons and neutrons isn't too different we can determine how many neutrons an atom has by subtracting the number of protons from its atomic mass.
Sulfur has 16 protons, so 35-16 = 19. So there are 19 neutrons present.
