43. Radioactive decay is also a first order process. For example, phosphorous-32, which is used extensively in biochemistry and medicine, decays with a half-life of 14.29 days. When using the rate law for radioactive decay, the concentration could be used, but frequently the mass of the material is used. Suppose that we have a sample of phosphorous-31. After 10 days, 41 mg of phosphorous-32 is present. What was the original mass of the phosphorous-32? (Answer: 67 mg) 67 mg)
