Question

The mass of a nitrogen molecule is 28.02 u. Find its mass in kg.

Answer 1

Answer:

Explanation:

A mole of N2 is approximately 28 g, and Avogadro’s number is approximately 6.022 x 10^23, so about 4.65 x 10^-23 g or 4.65 x 10^-26 kg.

If you need better accuracy, look up more accurate molar mass for N2 and Avogadro’s number .
