Question

The student in question 4 weighed the dry tablet before the reaction and found its mass to be 3.98 grams. Using the mass of the tablet that remained from question 4, what was the mass of gas released?

Answer 1

The mass of the gas released can be determined by subtracting the mass of the tablet that remained after the reaction from the mass of the dry tablet before the reaction.

Step-by-step explanation:

The mass of the gas released can be determined by subtracting the mass of the tablet that remained after the reaction from the mass of the dry tablet before the reaction. In this case, the mass of the tablet before the reaction was 3.98 grams. Let's say the mass of the tablet that remained after the reaction was 2.5 grams. To find the mass of the gas released, we subtract the mass of the tablet that remained from the initial mass:

Mass of gas released = Mass of tablet before reaction - Mass of tablet that remained = 3.98 g - 2.5 g = 1.48 g
