Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.M is molar mass.
Since you're taking hydrogen gas, you have a diatomic gas
u can also think of it this way , if i take 1kg of Hydrogen and 1g of hydrogen under same conditions and ignoring micro interacctions it will have same rms
so M cant be total mass
and anyways it is molar mass
but its helium
nvm
Oh crap I misread. Should be 4
I guess something cancelled
hm
yeah but i read this
is this wrong then
@Opt
Yeah, that's if you use pressure. If you have RT, you need to account for the number of moles, so the denominator basically becomes mass/n = molar mass
ohh got it thanks....and it should be 4 instead of 2 in the solution right
