Answer:

Percentage error = $\frac{(64 - 58)}{58}$ x 100%

Explanation:

In order to calculate the percentage error in the student's calculation, the following formula will be used:

Percentage error = $\frac{(experimental molar mass - theoretical molar mass)}{theoretical molar mass}$ x 100%

experimental molar mass = 64 g/mol

theoretical molar mass = 58 g/mol

Hence, the expression becomes:

Percentage error = $\frac{(64 - 58)}{58}$ x 100%
