If water with the mass of 15.0 grams is heated into water vapor in a closed system such as a closed glass jar, what is the mass of the gas after the water completely vaporizes?

A) 13.5 grams
B) 15.0 grams
C) 16.5 grams
D) The mass cannot be determined without knowing the volume.

15.0 g H2O weighs 15.0 g whether it is ice, liquid, or vapor.

The correct answer is B, trust me.

no, it's c

The correct answer is B. (15.0 grams) Because The mass stays the same.

The answer is 15.0 grams because the mass doesn’t change no matter what

Lol. But seriously are you ok XD

What do you mean @ Dr.Bob

the answer is b

To determine the mass of the gas after the water completely vaporizes, we first need to understand the concept of conservation of mass in a closed system. According to this principle, the total mass of the system remains constant.

In this case, we start with water that has a mass of 15.0 grams. As it is heated and vaporizes into gas, the water molecules transform from a liquid state to a gaseous state. However, the mass of the system remains the same, as no mass is lost or gained during the phase change.

Therefore, the correct answer is B) 15.0 grams. The mass of the gas will be equal to the initial mass of the water before vaporization.

Woah Mr.falcon... are you okay? did you take your medication???
