4 The chemical element einsteinium-253 naturally loses its mass over time. A sample of einsteinium-253
had an initial mass of 320 grams when we measured it. The relationship between the elapsed timet, in
days and the mass. M6), in grams left in the sample modeled by the following function (Level 1-2)
M(O) = 320 (0.25). The sample loses % of its mass every
days
