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.
<u>Answer:</u> The number of moles of nitrogen gas produced are 10.07 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
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:
Hence, the number of moles of nitrogen gas produced are 10.07 moles
