Which of the following contains maximum number of molecules?
Answers
Answer:
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
Explanation:
For a molecule,
molecular weight in grams = Avogadro's number(N
