Dimas [21]

The question is incomplete, the complete question is:

A chemist measures the amount of iodine solid produced during an experiment. He finds that 8.31 g of iodine solid is produced. Calculate the number of moles of iodine solid produced. Round your answer to the correct number of significant digits.

<u>Answer: </u>The number of moles of solid iodine produced is 0.0327 moles

<u>Explanation:</u>

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ ......(1)

Given mass of solid iodine = 8.31 g

Molar mass of solid iodine = 253.8089 g/mol

Plugging values in equation 1:

$\text{Moles of solid iodine}=\frac{8.31g}{253.8089g/mol}=0.0327mol$

Hence, the number of moles of solid iodine produced is 0.0327 moles
