Homework Statement
[/B]
You find a 1kg piece of rock containing 3 elements:
Fakium with 50 protons and 52 neutrons
imaginium with 52 protons and 48 neutrons
madeupium with 51 protons and 51 neutrons
Fakium is known to be radio active, Which of the other two elements could be the decay product and why?
On January 1st 2016 at 9am, you take a piece of the rock into the lab and measure that it is comprised of 0.5kg of fakium, 0.2kg imaginium, and 0.3kg madeupium. Exactly 24 hours later, you do the same measurement and find that the mass of fakium is now 0.48kg. What is the half life of fakium?
How long will it take until there is only 0.1kg of fakium left in the rock??

The Attempt at a Solution
Im dying over here but I know I can do this. If anyone is willing to help me I am willing to help myself too.
I believe Madeupium would be the decay product because it has decayed to 51 protons.
Im still working on the rest smh...
