A chemist determines by measurements that .060 moles of nitrogen gas participate in a chemical reaction. Calculate the mass of nitrogen gas that participates. Be sure your answer has the correct number of significant digits.

1.7 g N₂

Explanation:

In order to convert moles of nitrogen gas (N₂) to grams, we'll use its molar mass:

0.060 only has two significant digits, so the reported answer should have two significant digits as well. Meaning the answer is 1.7 g.

consider the reaction below.
