Question

Verify by calculating the following:
I
a. Number of molecules in 100 g of NH3 is more than 100 g of N2.
b. 60 g of carbon and 60 g of Mg elements have a molar ratio 2:1.

Answer 1

Answer:

a. 100g N2 contains = 100/28 moles

number of molecules = 100/28 x 6.022 x 10^ 23

number of atoms = 100/28 x 6.022x 10^23x2 = 43.10x10^ 23
