fast and explain how to solve half life

a 208 grams sample of sodium-24 decays to 52 grams in 30 hours. what is the half-life
of this radioactive sample?

Think about how you can use le chatelier’s principle to find possible solutions to the design problem. describe at least two ways to increase the yield (amount) of ammonia based on this principle.

Amixture with the same composition throughout is!
