In which type of system can the total mass of a reacting sample be measured as remaining constant without accounting for matter exchanged with the surroundings?

Answer and explanation

Correct answer: In a closed system

A closed system does not exchange matter with its surroundings. Thus, the total mass of the reacting sample remains constant; in an open system, matter such as a gas may escape or enter and affect the measured mass.
