Question

Lowest number of molecules

Answer 1

Answer: The least number of molecules are contained in :

A . 2 g hydrogen.

B . 8 g oxygen.

C . 4 g nitrogen.

D . 16 g CO2​

Explanation: The formula can be represented as the total number of molecules is equal to the number of moles X N (Avogadro's constant). The molecular mass of methane is 16g, Co2 is 44g, N2 is 28g and H2 is 6.023X10 power 23. Hence the H2 contains the maximum molecules
