Question

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 1

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 %.
