Madame Curie is famous for the discovery of radium and her pioneering work on radioactivity. The half-life of radium molar weight = 226g) is 1600 years. What is the decay rate in curies) of 5.0g of radium?

Question

Quizplus · Accepted Answer

The decay rate is given by the equation:```decay rate = (ln 2 / half-life) * amount```where:* ln 2 is the natural logarithm of 2 (approximately 0.693)* half-life is the time it takes for half of the radioactive substance to decay* amount is the amount of radioactive substanceIn this case, the half-life of radium is 1600 years and the amount of radium is 5.0g. Plugging these values into the equation, we get:```decay rate = (0.693 / 1600 years) * 5.0g = 4.95 Ci```Therefore, the decay rate of 5.0g of radium is 4.95 Ci.
