The half-life of cesium-137 is 30 years. Suppose that we start with 90 grams of cesium-137 in a storage pool.
How many half-lives will it take for there to be 10 grams of cesium-137 in the storage pool? (Round your answer to two decimal places.)
How many years is that? (Round your answer to one decimal place.)
