Chapter 2, Problem 2.65QP
The element francium (Fr) was the last element of the periodic table discovered in nature. Because of its high radioactivity, it is estimated that no more than 30 g of francium exists at any given time throughout the Earth’s crust. Assuming a molar mass of 223 g/mol for francium, what is the approximate number of francium atoms in the Earth’s crust?
