What is the mass of a nitrogen molecule in kg?
Understand the Problem
The question is asking for the mass of a nitrogen molecule expressed in kilograms. To answer this, we need to find the molecular weight of nitrogen (N2) and convert it from atomic mass units (amu) to kilograms.
Answer
4.65 x 10^-26 kg
The mass of a nitrogen molecule (N2) is approximately 4.65 x 10^-26 kg.
Answer for screen readers
The mass of a nitrogen molecule (N2) is approximately 4.65 x 10^-26 kg.
More Information
The value 4.65 x 10^-26 kg is derived from dividing the molar mass (28 g/mol) by Avogadro's number (6.022 x 10^23 molecules/mol) and converting grams to kilograms.
Tips
A common mistake is confusing the atomic mass of nitrogen (14) with the molecular mass of N2 (28). Always ensure to convert molar mass to kg using Avogadro's constant.
