Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.

A) At this rate, what fraction of its mass would Io lose in 4.5 billion years? *Express your answer in two significant figures*
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 in two significant figures*

Seconds in 4.5 billion years = 1.42006167 × 1017

Mmass of Io = You'll have to look it up!

1. (Seconds * 1000) / (mass of Io) = your answer.

2. No idea Confounded Face

It's basic math.

Lo's mass is about 9 x 1022 kg.

Calculate how many kg it loses in a year (you know the rate per second, just convert). Then you can figure out how much it would lose in the next 4.5 billion years. And, you can figure out how long it would take to lose 1% of its mass.

Mass of Io: 9 x 1022 kg

1% of that is 9 x 1020 kg.

1000 kg is 1 x 103 kg.

Now, divide and conquer Wink Face
