Given data
glass mas s= 200 gram
chemical mass = 500 gram
total mass = 700 gram
to find out
what is the total mass after chemical burn

we have given 200 gram + 500 gram = 700 gram
and we know here according to question that
container is sealed so total mass remain in container before burning and after burning
no air will release in seal container so
mass will be same as 700 gram
hence the total mass after chemical burn is 700 gram
