An element 7A14 exists as diatomic gas in nature which is relatively inert and forms 78% of earth’s atmosphere.
(a) Identify the gas and write its molecular formula. Write the formulae of its nitrite and nitrate ions.
(b) How many moles of this gas would contain 12.044 × 1023atoms of this element? (Avogadro’s no. = 6.022 × 1023)
(c) Calculate the molecular mass of
(i) NH4 NO3 and (ii) HNO3
(Given atomic masses N = 14 u, O = 16 u, H = 1u)
