Avg difficulty 2.5

Data from the appendices and the periodic table may be needed for these problems.

50V^{\text{50}} \text{V} has one of the longest known radioactive half-lives. In a difficult experiment, a researcher found that the activity of 1.00 kg of 50V^{\text{50}} \text{V} is 1.75 Bq. What is the half-life in years?
