Question

A volume is measured experimentally as 4.26mL. what is the percentage error, given that the correct value is 4.15mL

Answer 1

% error = | accepted value - experimental value | / accepted value × 100

Step one- | 4.15mL - 4.26mL | = 0.11

Step two- 0.11 / 4.15 = 0.027

Step three- -0.027 × 100 = 2.7%

Answer 2

Answer: The percentage error is 2.65 %.

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 volume = 4.26 mL

Accepted value of volume = 4.15 mL

Putting values in above equation, we get:

`\%\text{ error}=(|4.26-4.15|)/(4.15)* 100\\\\\%\text{ error}=2.65\%`

Hence, the percentage error is 2.65 %.
