Question

Which contain max number of molecules 1gco2,1gn2,1gh2,1gch4?

Answer 1

Answer:

If given compounds are taken in same amount then the one with lowest molar mass will have higher no. of molecules

as we know

no. of moles= given mass / molar mass

no. of molecules is nothing but

no. of moles * Avagadros no.

so no. of molecules inversely proportional to molar mass when given mass is same for different compounds

here H2 has least molar mass

hence it will have max molecules
