The percent error of Shirley's estimate is 21.74%
<h3>Calculating pecent error</h3>
Given the following parameters
- Actual length = 23 inches
- Estimated length = 18in
% error = actual-estimated/actual * 100
% error = 23-18/23 * 100
% error = 500/23
% error = 21.74%
Hence the percent error of Shirley's estimate is 21.74%

7.7278 g/ml is the most accurate density of the substance.
<h3>What is density?</h3>
It is define as the quantity per unit volume, unit area, or unit length.
i.e. the mass of a substance per unit volume.
Mathematically,
----- equation (1)
Where,
p is the density
m is the mass
v is the volume
According to the question,
Mass = 27.82 grams
Volume = 3.6 ml
By substituting the Value of m and v in equation 1.


Therefore,
The most accurate density of the substance in g/ml is 7.7277777 g/ml.
