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.

The balanced chemical
reaction will be:
<span>2C6H6 + 15O2 = 12CO2 + 6H2O</span>
We are given the amount of benzene to react with oxygen gas.
This will be our starting point.
<span>10.47 g C6H6 ( 1 mol C6H6 / 78.1074 grams C6H6) (15 mol O2/2 mol C6H6 ) (
32 g O2 / 1 mol O2) = 32.1711g O2</span>
