Your calculated density of aluminum is d = 2.76 g/cm3. Aluminum’s accepted density is 2.70 g/cm3. Without writing the "%" sign, calculate the percent error up to two decimal places:

Answer:T he percentage error up to two decimal places is 2.22 %.

Step-by-step explanation:

To calculate the percentage error, we use the equation:


\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}* 100

We are given:

Experimental value of density=
2.76g/cm^3

Accepted value of density =
2.70g/cm^3


\%\text{ error}=\frac{[{2.76 - 2.70}|}{2.70}* 100=2.22%

Hence, the percentage error is 2.22 %.
