Answer:
5.104%
Step-by-step explanation:
Given:
The accepted value for the mass density = 4.80 g/cc
Observed values:
5.13 g/cc
4.98 g/cc
5.06 g/cc
5.01 g/cc
Total number of observed values = 4
Mean of the observed values = ( 5.13 + 4.98 + 5.06 + 5.01 ) / 4 = 5.045 g/cc
Now,
The percentage error is calculated as:
%
on substituting the values, we get
%
or
Percentage error = 5.104%

Answer:
2.5% and 2.5 · 10^-3, 0.25, 2/5, √5
Step-by-step explanation:
0.25, 2/5, 2.5 · 10^-3, 2.5%, √5
Now let's list them all in the same form, why not decimals.
0.25 = 0.25
2/5 = 4/10 = 40/100 = 0.4
2.5 · 10^-3 = 2.5 · 0.01 = 0.025
2.5% = 0.025
√5 ≅ 2.236
