sodium-24 has a half life of 15 hours,how much of a 50 gram sample will be left after 60 hours

0.014 grams

To determine how much of a 50-gram sample of sodium-24 will be left after 60 hours, we need to use the concept of half-life.

The half-life of sodium-24 is given as 15 hours. This means that after every 15 hours, the amount of sodium-24 will reduce by half.

So, let's break down the 60-hour time period into four 15-hour intervals.

After the first 15 hours (1 half-life), the amount of sodium-24 remaining will be 50 grams / 2 = 25 grams.

After the second 15 hours (2 half-lives), the amount of sodium-24 remaining will be 25 grams / 2 = 12.5 grams.

After the third 15 hours (3 half-lives), the amount of sodium-24 remaining will be 12.5 grams / 2 = 6.25 grams.

After the fourth 15 hours (4 half-lives), the amount of sodium-24 remaining will be 6.25 grams / 2 = 3.125 grams.

Therefore, after 60 hours, there will be approximately 3.125 grams of the original 50-gram sample of sodium-24 remaining.
