Chemistry Calculation: How Many Moles of Nitrogen in Nitrous Oxide?

How many moles of nitrogen, N, are in 71.0g of nitrous oxide, N2O?

Final answer:There are approximately 2.366 moles of nitrogen (N) in 71.0g of nitrous oxide (N2O).

Final answer:There are approximately 2.366 moles of nitrogen (N) in 71.0g of nitrous oxide (N2O).

Reflecting on the chemistry calculation provided, we can see that determining the number of moles of nitrogen in a given mass of nitrous oxide involves understanding the molar mass and applying the formula for calculating moles. In this case, the molar mass of N2O was calculated by adding the atomic masses of nitrogen (N) and oxygen (O).

The process of calculating moles from mass requires the use of the formula: Moles = Mass (g) / Molar mass (g/mol). By substituting the given mass of 71.0g and the molar mass of N2O (30.01 g/mol) into the formula, we arrived at the answer of approximately 2.366 moles of nitrogen in 71.0g of nitrous oxide.

Understanding and applying these fundamental concepts in chemistry calculations is essential for accurately determining the quantity of substances in a chemical reaction or sample. By practicing and mastering these calculations, students can develop a strong foundation in chemistry and analytical skills that are crucial in various scientific fields.
