This is a problem of determining mole ratios in the stoichiometric equations.

(i) Mass of O2

We have moles of KClO3 = 1.50mol

Mole ratios of KClO3 : O2 = 2:3

Thus moles of O2 


= 2.25mol of O2


Moles 


Therefore Mass of O2 = Moles x MM

= 2.25mol x 32g/mol

= 72g

(ii) Moles of KClO3


Moles of O2 


Mole ratios of O2:KClO3 = 3:2


Moles of KClO3 


(ii)Mass of KClO3

We are given moles of KCl = 2.75mol

Mole ratios of KCl : KClO3 = 2:2

Thus moles of KClO3 


Mass = Moles x MM

= 2.75mol x 122.55g/mol

= 337.013g
