1.	How many grams are there in the following ? (i) 1 mole of chlorine molecule, Cl_(2) (ii) 2 moles of sulphur molecules, S_(8) (iii) 4 moles of ozone molecules, O_(3) (iv) 2 moles of nitrogen molecules, N_(2)
Answer» Solution :(i) 1 mole of CHLORINE molecule `Cl_(2)` Atomic MASS of chlorine = 35.5 g `"Mass of 1 mole of chlorine"="Atomic mass"xx"ATOMICITY"` `=35.5xx2=71g` (ii) 2 moles of sulphur molecules `S_(8)` Atomic mass of `S_(8)=8xx32=256g` `"Mass of 2 moles of "S_(8)="Atomic mass "xx"Number of moles"` `=256xx2=512g` (III) `"4 moles of OZONE molecules "O_(3)` `"Atomic mass of "O_(3)=3xx16=48g` (iv) `"2 moles of Nitrogen molecules "N_(2)` `"Atomic mass of "N_(2)=2xx14=28g` `"Mass of 2 moles of Nitrogen"=28xx2=56g`
