Interpretation Introduction

Interpretation:

Among the given statements, the one which is true is to be stated.

Concept Introduction:

According to the law of conservation of mass, the mass of any substance that is present in the closed system remains constant because there is no exchange of matter or energy takes place in a closed system.

### Explanation of Solution

Reason for correct option:

(b) The balance will read the value of mass for the chemical equals to 250.0g only because according to the law of conservation of mass, no exchange of mass will take place between the closed system and the surrounding
