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

Maximum mass = B, Minimum mass Cl

Explanation

(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 gram atom of iodine `= 127.0 g`
0.256 gram atom of iodine `= 127.0 xx 0.256 = 32.512 g`
Maximum mass of = B Minimum mass = C.
