Question

2 Calculate the
mass
of 3.011 1024 molecules of
nitrogen gas. Atomic mass =14​

Answer 1

Explanation:

Atomic mass : N=14u) Thus, the mass of 1 mole of nitrogen molecules is 28 grams. Now, 1 mole of nitrogen molecules contains 6.022×1023 molecules. This mass of 3.011×1024 molecules of nitrogen is 140 grams.
