Calculate the total number of electrons present in 1 g of dinitrogen g

1.	Calculate the total number of electrons present in 1 g of dinitrogen gas
Answer» Answer Mass of the nitrogen = 1.4 g Molar mass of nitrogen = 28 g mol–1 Therefore amount of nitrogen = 1.4 / 28 = 0.05 mol Number of nitrogen molecule in 0.05 mol = 6.023 x 1023 x 0.05 = 3.0115 x 1022 Also number of electrons in one molecule of nitrogen = 14 Therefore, total number of electrons in 1.4 g of nitrogen = 3.0115 x 1022x 14 = 4.22 x 1023

Calculate the total number of electrons present in 1 g of dinitrogen gas

Answer»

Answer

Mass of the nitrogen = 1.4 g

Molar mass of nitrogen = 28 g mol–1

Therefore amount of nitrogen = 1.4 / 28 = 0.05 mol

Number of nitrogen molecule in 0.05 mol

= 6.023 x 1023 x 0.05

= 3.0115 x 1022

Also number of electrons in one molecule of nitrogen = 14

Therefore, total number of electrons in 1.4 g of nitrogen

= 3.0115 x 1022x 14

= 4.22 x 1023
