Question

The accepted density of copper is 8.69 g/ml. Calculate the % error if you measured 8.50 g/mL.

Answer 1

Answer: 2.2235%

Explanation:

The formula for percentage error os written as:

(Approximate value)/Exact value × 100

Here,

Approximate value = 8.50g/mL

Exact value = 8.69g/mL

Slotting the values into the formula will be:

= (Approximate value)/Exact value × 100

= (8.69 - 8.50)/8.50 × 100

= 0.19/8.50 × 100

= 0.0223529 × 100

= 2.2235%
