The heat of vaporization of a substance is
2900 J/g at its boiling point of 313�C. How
much of this substance can be vaporized if
58700 J of energy are available?
2900 J/g x ??g = 58700 J.
Solvr for ?? g.
To calculate the amount of substance that can be vaporized, we need to use the formula:
Amount of substance vaporized = Energy available / Heat of vaporization
Given:
Heat of vaporization = 2900 J/g
Energy available = 58700 J
Let's substitute these values into the formula:
Amount of substance vaporized = 58700 J / 2900 J/g
To find the amount of substance in grams, we need to divide the total energy available by the heat of vaporization:
Amount of substance vaporized = 20.24 g
Therefore, 20.24 grams of the substance can be vaporized with 58700 J of energy available.
