Students conduct an experiment in which steel wool is burned in a closed test tube. The steel wool reacts with an amount of oxygen equal to 1.43% of the mass of the steel wool. What is the correct value for the missing mass in the table?
The value of the mass in the missing table is 43.48 g. Since it is in a closed system, nothing would escape. The law of conservation of mass would state that the products mass would equal the reactants mass.
