Scientists have discovered a new type of metal compound. They have roughly 15 grams of this compound, which has a half-life of 16 hours (it loses half of its mass every 16 hours). Approximately how much of this substance will be left after 48 hours?

R ==15  x  2^-(48/16)

R ==15  x  2^-3

R== 1.875 g - what remains of the metal compound after 48 hours.
