Expert Answer
(i) 1 gram atom of Nitrogen = 14 g
(ii) One mole of Calcium = 40.08 g
(iii) One atom of Silver = 107.87 amu = 107.87 × 1.66 × 10-24 g = 179 × 10-24 g
(iv) One mole of O2 molecule = 32 g
(v) 1023 atoms of Carbon = 1023 × 12 × 1.66 × 10-24 ≈ 2 g
(vi) one g of Iron = 1 g
if we arrange all above items in increasing order of mass
( iii ) < ( vi ) < ( v ) < ( i ) < ( iv ) < ( ii )
Answer :- (d) both (b) and (c) are correct
