Question

the accepted density for copper is 8.96 g/ml. what is the percent error if a student obtained a density for copper of 8.79 g/ml? round to correct sigfigs. (1 point) 1.897% -1.897% -0.0190% 1.90%

Explanation:

Step1: Calculate the error

Error = |Experimental value - Accepted value|
Error = |8.79 - 8.96| = 0.17

Step2: Calculate the percent error

Percent error formula is $\frac{\text{Error}}{\text{Accepted value}}\times100\%$
Percent error = $\frac{0.17}{8.96}\times100\%$
Percent error = $\frac{17}{8.96}\%$
Percent error $\approx1.90\%$ (rounded to three significant figures as 8.79 has three significant figures and 8.96 has three significant figures)

Answer:

1.90%
