x<=............5*g

Explanation:

There are x*g KClO_3...........

And we recover (2.96*g)/(74.55*g*mol^-1)=0.0397*mol with respect to KCl.

And (1.92*g)/(15.999*g*mol^-1)=0.120*mol with respect to "oxygen".

Clearly, there were 0.0397 "mol" with respect to KClO_3.

And thus x, "mass of potassium chlorate" = 0.0397*molxx122.55*g*mol^-1=4.86*g
