Answer:
The percentage difference between the two methods is 2.95%.
Step-by-step explanation:
The percentage difference is the difference between two values divided by the average of the two values. Shown as a percentage.
The difference means to subtract one value from another and the average is given by
[tex]average=\frac{first \:value+second \:value}{2}[/tex]
Given
[tex]d_1 = 2.75 \:{g/cm^3}\\d_2 = 2.67 \:{g/cm^3}[/tex]
The difference is [tex]2.75-2.67=0.08[/tex]
The average is [tex]\frac{2.75+2.67}{2} =2.71[/tex]
And the percentage difference is
[tex]\frac{0.08}{2.71} \times100\%=2.95\%[/tex]
