Answer:

If 4.9 g of potassium chlorate is used then it gives O2 and KCL.

From the problem statement it is understood that 1.92 g of Oxygen is produced and the residual mass is 2.96g.

Mass of the products come to 1.92+2.96=4.88g.

Since 4.88 g is very close to 4.9 g, therefore it can be deduced that the conservation of mass is valid in this case.
