Best ResponseYou've already chosen the best response.2molar mass of N2H4 = 2(14)+4(1) =32 moles of N2H4 in 67.3gm sample =67.3/32 number of moles of H in 1 mole of N2H4 is 4 so number of moles of H in 67.3/32 moles of N2H4 =4(67.3/32)=67.3/8 number of atoms of H in 67.3/8 moles of H = 67.3/8 x Avagadro number =67.3 /8 x 6.023 x 10^(23) =5.06 x 10^24 atoms :)
