Question

what is the mass of 0.2 mole of nitrogen atoms​

Answer 1

Step-by-step explanation:

Mass of one mole of nitrogen atom=14 u

Therefore mass of 0.2 mole of nitrogen =0.2 *14

i.e 2.8 u.

Or , number of mole =(wt)/atomic mass

Then (wt)=no.of mole*atomic mass

Since given no.of mole=0.2

And atomic mass of nitrogen=14

Therefore, (wt) nitrogen=0.2*14=2.8

Answer 2

Answer:

2.8

Step-by-step explanation:

Mass of one mole of nitrogen atom=14 u

Therefore mass of 0.2 mole of nitrogen =0.2 *14

i.e 2.8 u.

Or , number of mole =(wt)/atomic mass

Then (wt)=no.of mole*atomic mass

Since given no.of mole=0.2

And atomic mass of nitrogen=14

Therefore, (wt) nitrogen=0.2*14=2.8
