Question

Determine the number of molecules in 50 g of HCl , 25 g of

nitrogen gas​

Answer 1

Answer:

8.31 molecules of HCL and 21.5 molecules respectively

Explanation:

NUMBER OF ATOMS/MOLECULES= GIVEN MASS/MOLAR MASS*NA (avagadro constant 6.022*10^23)

Molar Mass of HCL(1+35.5=36.5)

Molecules= 50/36.5*6.022*10^23

=1.38* 6.022*10^23

8.31*10^23 molecules

Nitrogen molecules= 25/7*6.022*10^23

=3.57*6.022*10^23

=21.5 atoms
