Question

Which has maximum no. of molecules among the following and why? a)44g of CO2 b)48g of O2 c)8g of H2 d)16g of SO2

Answer 1

Hydrogen have maximum number of molecule. ...

Find their moles..
Then Multiply moles with avagadro number you will get Number of molecules

Answer 2

look when the question asks u to calculate the maximun no of molecules or atoms in a substance then this doesn't mean that you have to really calculate the number of atoms or molecules by multiplying them with avogadro number....there is no need of avogadro number when you r opting an mcq bcz u have to utilise ur time very carefully when u r answering mcqs...
the strategy is that, the more the number of moles maximum will be the number of atoms and molecules......
I have shown this in above attachment....so next time when u r doing this type of questions or mcq, whatsoever, keep this strategy in mind.....I promise it will save ur time....
