34. Which of the following pairs contain equal number ofatoms?() 11.2 cc of the N2 and 0.015 g of nitric oxide(2) 22.4 litres of nitrous oxide and 22.4 litres of nitricoxide3) ole l HCl and and 0.5 m mole of H,S(4) 1 mole of H,02 and 1 mole of N20 |

Answer» 1) 11.2 cm³ is 11.2/1000L, so moles will be 1/2000= 0.005moles of N2 and for nitric oxides the formula is NO(molecular mass = 30) is 0.015/30 = 0.005moles... so, option 1 matches.. the same no. of moles for both the compound.. having 2 atoms each. |
