Calculate the mass of : (i) 1.2 gram atom of oxygen (ii) 5.2 gram ato

1.	Calculate the mass of : (i) 1.2 gram atom of oxygen (ii) 5.2 gram atom of iodine (iii) 5.6 gram atom of chlorine.
Answer» SOLUTION :(i) 1.0 gram atom of oxygen = 16.0 g 1.2 gram atoms of oxygen `= 16.0 XX 1.2 = 19.2 g` (ii) 1.0 gram atom of iodine = 127.0 g 5.2 gram atom of iodine `= 5.2 xx 127.0 = 660.4 g` (III) 1.0 gram atom of CHLORINE `= 35.5 g` 5.6 gram atom of chlorine `= 5.6 xx 35.5 = 198.8 g`
