since hydrogen gas is given so we have to take H2 gas
so solution is
2*2.5*6.022*10^23
30.11*10^23 = 3.011*10^23
so solution is
2*2.5*6.022*10^23
30.11*10^23 = 3.011*10^23
why did you multiply with 2 also
cause it is given that is it a gas ,and hydrogen gas means H2
okay
just check it ,i think it's correct
