The average banana contains 0.436 g of potassium, and 0.012% of naturally occurring potassium is 40K, which has a half-life of 1.248 × 10^9 years and an atomic mass of 39.964 u. What is the activity of a freshly picked bunch containing three bananas? The activity is the number of 40K decays that occur per unit time. Activity is commonly measured in units of Becquerel (Bq), which is defined as decays per second. Recall that the atomic mass unit u...

Uranium has 3 naturally occurring isotopes; 238U, 235U, and 234U. Roughly 99.2745% of uranium is U-238 and 0.7200% is U-235. What is the average mass of an U atom? You may assume that the mass of each isotope is equal to its mass number. Report your answer to 6 sig figs. How many protons, neutrons, and electrons does 235U have?
