The percentage error is 1.33 %.
To calculate the percentage error, we use the equation:
We are given:
Experimental density of vanadium =
Accepted density of vanadium =
Putting values in above equation, we get:
Hence, the percentage error is 13 %.
The theoretical value for the density of vanadium is 6.11 g/cm3 while the experimental value determined in the laboratory is 6.9 g/cm3. To calculate the percentage error, the following formula is used
