Static charge can interfere with the production of plastic products by attracting dust and dirt. to reduce it, manufacturers expose the area to polonium-210, which has a half-life of 138 days. How much of a 25.0-g sample will remain after one year (365 days)?

N = N0(1/2)t/T = (25)(1/2)365/138 ≈ 4.0 g
Would 4.0 g be correct?
