A reaction produced 94.9 grams of nitrogen dioxide gas. However, the calculated theoretical value indicates that 100.10 grams of nitrogen dioxide gas should have been produced. What is the percent error?

Answer 1

To find the percent error, we use the formula:

percent error = (|experimental value - theoretical value| ÷ theoretical value) x 100%

Substituting the given values, we get:

percent error = (|94.9 g - 100.10 g| ÷ 100.10 g) x 100%
percent error = (5.20 g ÷ 100.10 g) x 100%
percent error = 5.20%

Therefore, the percent error is 5.20%.
