In a laboratory activity, the density of a sample of vanadium is determined to be 6.9 g/cm3 at room temperature. what is the percent error for the determined value?

a. 0.15%
b. 0.87%
c. 13%
d. 15%

Answers

D) 15%
Hope this helps :)

The percentage error is 1.33 %.

Explanation:

To calculate the percentage error, we use the equation:

\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100

We are given:

Experimental density of vanadium = 6.9g/cm^3

Accepted density of vanadium = 6.11g/cm^3

Putting values in above equation, we get:

\%\text{ error}=\frac{|6.9-6.11|}{6.11}\times 100\\\\\%\text{ error}=13\%

Hence, the percentage error is 13 %.

13%

Explanation:

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

percentage error = ((|experimental value – theoretical value|)/theoretical value) *100

percentage error = ((6.9-6.11)/6.11) * 100

= 13%
