Calculate the mass of (a) 1.6 gram atoms of oxygen C (b) 5.6 gram atoms of sulphur c) 2.4 gram atoms of iodine.
(Atomic masses : O = 16, S = 32,I = 127)

Answer

A, B, C, D

Explanation

(a) 1.6 gram atoms of oxygen `=16 xx 1.6 = 25.6`g
(b) 5.5 gram atoms of sulphur `=32/1 xx 5.6= 179.2`g
( c) 2.4 gram atoms of iodine `=127 xx 2.4 = 304.8`g
