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)`

Explanation

(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`
