Question

mass of
1) nitrogen atom.
2) nitrogen molecule.
3)1 mole of nitrogen atom.
4)1mole of nitrogen molecule.
plz answer me​

Answer 1

Answer:

1) Mass of one mole of nitrogen atoms is 14g

Molar mass of Nitrogen = 14g/mole

#Mass of 1 mole of Nitrogen = 14g

#1 mole of nitrogen contains 6.022×1023 atoms (Avogadro’s number)

#Mass of 6.022 × 1023 atoms of nitrogen = 14 grams

#Mass of 1 atom of nitrogen = 14g/(6.022 × 1023 atoms)

#Mass of 1 atom of nitrogen = 2.325 × 10-23

Answer 2

Answer:

Answer:for its one mole it is of 28gram. according to mole concept in one mole there is 6.022*10^23 moles are present. so mass of 1 molecule of nitogen gas is 28/(6.022*10^23) gram.
