Answer:
A = 0.75 gram or 1 gram
Step-by-step explanation:
The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).
We can use the following formula for half-life of
to find out how much is left from the original sample after 2,292 years:

where:
<em>A</em> is the amount left of an original gram sample after <em>t</em> years, and
is the amount present at time <em>t</em> = 0.
The half-life of
is the time <em>t</em> at which the amount present is one-half the amount at time <em>t </em>= 0.
If 1 gram of
is present in a sample,
Solve for A when t = 2,292:
Substituting
= 1 gram into the decay equation, and we have:
A = 0.75 g or 1 g
