Question
two flasks A and Bcontain helium and hydrogen gases at 270C and 1 atm pressure. If volume of each vessel is 2L then flask B contains....
(1) The same number of atoms as in B , (2) same weight of gasas in B , (3) dubble the number of atoms asin A (4)half of the number of atoms in A , ?
Joshi sir comment
answer by nikhil is correct
in his answer Na represents avagadro number not sodium
Read 1 Solution.
by the ideal gas eqn PV=nRT we get number of moles of H2 = nu of moles of He
in n moles of H2 there are n * 2 Na atoms ( A flask)
while in n moles of He there are n* Na atoms ( B flask )
so correct option is 4
