The platinum-191 reaction has a half-life of 3.0 days. If the initial radiation of a 191Pt sample measures 40 mCuries, what will it measure after 12 days? Include units in your answer. Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter the radiation in the box below.

The following graph shows the progression of a reaction between molecular hydrogen (H2) and molecular (I2) to produce hydrogen iodide (HI). Referencing the graph, answer the following four questions.   See the description for details “This image depicts a graph showing the progression of a chemical reaction between molecular hydrogen (H2) and molecular iodine (I2) to form hydrogen iodide (HI). The red line represents the concentration of H2(reactant). The black line represents the concentration of I2 (reactant). The red dashed line represents the concentration of HI (product).The vertical line marked “”A”” is used as a reference for further questions regarding the concentration progression over time.”
