A bottle containing a reagent was weighed to show a mass of 25.3658 g. Some material was carefully transferred to a reaction flask, and the bottle reweighed to show a mass of 22.1287 g. What mass of the material was transferred to the flask

3.2371 g

Explanation:

Step 1: Given data

Step 2: Calculate the mass of the material was transferred to the flask

Since the bottle is unaltered, the mass of the material transferred to the flask is equal to the difference between the initial mass of the system and the final mass of the system.

m = 25.3658 g - 22.1287 g = 3.2371 g

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
