The question is incomplete, here is the complete question:

A chemist measures the amount of nitrogen gas produced during an experiment. She finds that of 282. g of nitrogen gas is produced. Calculate the number of moles of nitrogen gas produced. Be sure your answer has the correct number of significant digits.

Answer: The number of moles of nitrogen gas produced are 10.07 moles

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of nitrogen gas = 282 g

Molar mass of nitrogen gas = 28 g/mol

Putting values in above equation, we get:

$\text{Moles of nitrogen gas}=\frac{282g}{28g/mol}=10.07mol$

Hence, the number of moles of nitrogen gas produced are 10.07 moles
