the actual density of iron is 7.874 g/ml. in a laboratory investigation, jason finds the density of a piece of iron to be 7.921 g/ml. what is the percent error that is associated with jasons measurement? -4.7% -0.6% 0.6% 4.7%

Answer

Explanation:

Step1: Recall percent - error formula

Percent error = $\left|\frac{\text{experimental value}-\text{actual value}}{\text{actual value}}\right|\times100%$

Step2: Identify values

The actual value of iron's density is $7.874$ g/mL and the experimental value is $7.921$ g/mL.

Step3: Substitute values into formula

Percent error = $\left|\frac{7.921 - 7.874}{7.874}\right|\times100%=\left|\frac{0.047}{7.874}\right|\times100%$

Step4: Calculate result

$\frac{0.047}{7.874}\approx0.006$, and $0.006\times100% = 0.6%$

Answer:

0.6%
