Question

The radius of a crystalline calcium ion was calculated to be 1.05 x 10⁻10m. The accepted value for this ion is 1.00 x 10⁻10m. What is the experiment's percent error?

A) 5%
B) 4.76%
C) 5.25%
D) 4.99%

Answer 1

The percent error of the experiment concerning the radius of a crystalline calcium ion is calculated as 5%, which is achieved by comparing the calculated value to the accepted value and applying the percent error formula.

Step-by-step explanation:

The percent error in an experiment can be calculated using the formula: percent error = (|experimental value - accepted value| / accepted value) × 100%. In this case, to find the percent error of the calculated radius of a crystalline calcium ion, we use the student's calculated value of 1.05 × 10⁻¹° m and the accepted value of 1.00 × 10⁻¹° m. The calculation will be as follows:

percent error = (|1.05 × 10⁻¹° m - 1.00 × 10⁻¹° m| / 1.00 × 10⁻¹° m) × 100% = (0.05 × 10⁻¹° m / 1.00 × 10⁻¹° m) × 100% = 5%. Therefore, the correct answer is A) 5%.
