Question

calculate the number of molecules and number of atoms present in 1g of nitrogen​

Answer 1

Answer:

Explanation:

The molecular weight of Nitrogen gas is about 28 g/mole and there are 6.02x10^23 molecules per mole. I get about 2.2x10^22 molecules 1 g of Nitrogen gas. I may have rounded a few numbers incorrectly, but there are a lot of molecules in 1 g of Nitrogen gas.

(OR)

Molecular weight of N2 contains NA molecules

(Molecular weight of N2 = 28 gram)

(NA molecules = 6.023* 10^ 23 molecules)

28 gram of N2 contains 6.023* 10^23 molecules

1 gram of N2 contains 6.023* 10^ 23/ 28 molecules = 2.15* 10^ 22 molecules

Answer 2

Answer: The number of molecules present in 1g of Nitrogen is 4.301*10^22.
