At the current loss rate, it will take io 28.3 billion years to run out of the sulfur dioxide gas.
We know that,
Sulfur dioxide currently makes up 1 % of Io's mass.
The mass of Io is 8.93*10^22 kg (Hint)
So, mass of sulfur dioxide = 1/100 * 8.93*10^22 kg
= 8.93*10^20 kg
Rate of loss of sulfur dioxide per second = 1000 kg
so, rate of loss of sulfur dioxide per year = 1000*60*60*24*365
= 3.154 * 10^10kg
Time taken for sulfur dioxide to loss these mass
= 8.93 * 10^20/3.154 * 10^10
= 2.83*10^10 years
=28.3*10^4 years
28.3 billion years
