1.	Which has the maximum and minimum mass ? (A) 25.6 g of oxygen (atomic mass = 16) (B) 2.56 gram atom of sodium (atomic mass = 23) (C) 0.256 gram molecule of water (molecular mass = 18) (D) 0.256 gram atom of iodine (atomis mass = 127)
Answer» SOLUTION :(A) 25.6 G of oxygen = 25.6 g (B) 1.0 GRAM atom of Na = 23.0 g 2.56 gram atom of `Na = 2.56 xx 23.0 = 58.88` g (C) 1.0 gram molecule of `H_(2)O = 18.0 g` 0.256 gram molecule of `H_(2)O = 0.256 xx 18.0 = 4.608 g` (D) 1.0 gramatom of iodine `= 127.0 g` 0.256 gram atom of iodine `= 127.0 xx 0.256 = 32.512 g` Maximum MASS of = BMinimum mass = C.
