C i think but you should pick it anyway
Half-life is a first-order reaction which means the rate of decay is constant. Using the supplied value of the half-life of 14c (5715 years), and that the <span>piece of ancient charcoal contains only 20% as much of the radioactive carbon as a piece of modern charcoal, the calculated "age" or timespan when the tree got burned is </span>13269.819062281 or simply, 13270 years ago.
The experimental value of Avogadro's number will be ±0.050.
<h3>What is the degree of accuracy?</h3>
The degree of accuracy refers to the extent to which a measurement is correct. Now we know that the measurement obtained by an instrument is as correct as its degree of accuracy.
Hence, given that the margin of error is about 0.050, the experimental value of Avogadro's number will be ±0.050.
