a ß particle is a(n) оо alpha particle O electron O positron

Half of the mass of a piece of wood just cut from a tree consists of carbon. The piece of wood emits 9322 electrons per minute and among the elements that compose it only one is radioactive. Assuming that in a tree the isotopic abundance of ¹4C is 1.3 x 10-¹2, 14 estimate the weight of the piece of wood in grams to 1dp
