how many grams of nitrogen -16 will br left from a 16g sample after 21.6 seconds if its half life is 7.2 seconds
Added by Aurora S.
Step 1
First, we need to determine how many half-lives have passed in 21.6 seconds. We can do this by dividing the total time by the half-life: 21.6 seconds ÷ 7.2 seconds/half-life = 3 half-lives Show more…
