Question: Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.
Part A: At this rate, what fraction of its mass would Io lose in 9.0 billionyears ? Express your answer using two significant figures.
Part B: Suppose sulfur dioxide currently makes up 1 % of Io's mass. When will Io run out of this gas at the current loss rate? Express your answer using two significant figures.
