Question

Which one contains max. No of molecules 1gco2, 1gN2, 1gH2, 1gCH4 ?

Answer 1

Answer:

Explanation:

1g H2 contains a maximum number of molecules.

The molecules present in the 1g CO2:

The molar mass of CO2 = 44g

The number of molecules

= 0.02NA

The molecules present in the 1g N2 :

The molar mass of N2 = 28g

The number of molecules

= 0.03NA

The molecules present in the 1g H2 :

The molar mass of N2 = 2g

= 0.5NA

The molecules present in the 1g CH4 :

The molar mass of CH4 = 16g

= 0.06NA

Thus, we can see that 1g H2 contains the highest number of molecules.
