Question

a sample of nitrogen contains 2.8×10^19 atoms of nitrogen. what is the mass of this collection of atoms?? the atomic mass of nitrogen is 14 amu.​

Answer 1

Answer:

1 mole nitrogen contains 6.02×10

23

nitrogen molecules.

Thus 14 gram nitrogen will contain 14/28.Na=0.5Na=3.01×10

23

nitrogen molecules. ( Molecular weight of nitrogen is 28)

Answer 2

$\bold \pink{answer}$

1 mole nitrogen contains 6.02×10²³ nitrogen molecules.

Thus 14 gram nitrogen will contain 14/28.N➡️ 0.5Na➡️3.01×10²³

nitrogen molecules. ( Molecular weight of nitrogen is 28)

Hope this helps you♥️
