Question

Calculate total no of electrons present in 1.4g of nitrogen gas

Answer 1

Answer:

7 electrons are present in the nitrogen gas.

Answer 2

1.4 g of nitrogen corresponds 10 1.6 / 22 is equal to 0.05 moles.

0.05 moles of nitrogen corresponds

to 0.05 × 6.023 raise to the power 23 = 3.011 raise to the power 22 molecules

ane molecules of nitrogen contains 14 electrons

1.4 g of nitrogen will contain 3.011 raise to the power 22 ×14=4.2154×10 raise to the power 23

electrons.
