Question

You were expected to create 150 mg of substance X, but after your experiment, you created 123 mg of substance X. What is your % error?

A. 18%
B. 22%
C. 82%
D. 13%

Answer 1

The percent error in the synthesis of substance X is calculated using the formula (|Experimental Value - Theoretical Value| / Theoretical Value) × 100%. Substituting the values, the percent error is found to be 18%, which is option A.

Step-by-step explanation:

The question asks to calculate the percent error for the synthesis of substance X. To find the percent error, you can use the formula:

Percent Error = (|Experimental Value - Theoretical Value| / Theoretical Value) × 100%

In this case:

• Theoretical Value (expected amount) = 150 mg
• Experimental Value (actual amount created) = 123 mg

Now, substituting the values into the formula, we get:

Percent Error = (|123 mg - 150 mg| / 150 mg) × 100% = (27 mg / 150 mg) × 100% = 18%

Therefore, the percent error in the synthesis of substance X is 18%, which corresponds to option (A).
