Question

labrotory begn to study wit 10 grams of a certain compound. after one year, the compound had decayed to total of 5 grams. after three years the compound had decayed to 1.25 grams. what is the decay facto (b) to describe this situation?

Answer 1

The decay factor (b) can be determined by comparing the initial mass of a compound to the mass after a given period of time. After one year, the decay factor is 0.5, and after three years, it is 0.125.

Step-by-step explanation:

The decay factor can be determined by comparing the initial mass of the compound to the mass after a given period of time. In this case, we can compare the initial mass of 10 grams to the mass after one year (5 grams) and three years (1.25 grams). To find the decay factor (b), we divide the final mass by the initial mass.

After one year: b = 5 grams / 10 grams = 0.5

After three years: b = 1.25 grams / 10 grams = 0.125
