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%
