Consider the following reaction, KClO(3)...

Consider the following reaction,
`KClO_(3)(s)rightarrow KCl(s)+(3)/(2)O_(2)(g)`
`SO_(2)(g)+(1)/(2)O_(2)(g)rarr SO_(3)(g)`
If yield of both reactions is `100%` and `67.2L` of `SO_(3)` is produced at STP, then minimum mass of `KClO_(3)` required in the reaction is (Molar mass of `KClO_(3)=122.5(g)/(mol)`)
