Your calculated density of aluminum is d = 2.69 g/cm3. Aluminum’s accepted density is 2.70 g/cm3. Without writing the "%" sign,

stepan [7]

Answer:

0.37 %

Explanation:

Given that:

Calculated density of aluminum = 2.69 g/cm³

Accepted density of aluminum = 2.70 g/cm³

$Error\ percentage=\frac {|Accepted\ value-Calculated\ value|}{Accepted\ value}\times 100$

Thus, applying values as:

$Error\ percentage=\frac {|2.70-2.69|}{2.70}\times 100$

<u>Percent error = 0.37 %</u>
