The unit for the heat of vaporization is J/g or Joules per gram of material. The amount of energy required = mass * heat of vaporization = 5.0 g * 5.0 J/g = 25.0 J (Q.E.D.)

How much energy is needed to melt 25.4grams of l2?
Iodine sublimes - it does not melt
How much energy is needed to melt 255.67 grams of ice?
80 calories per gram (called the latent heat of fusion) 80 x 255.67 = 20453.6 calories
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
How much energy is needed to melt 254 grams of l2?
This is a trick question because "I2" is the chemical symbol for MOLECULAR iodine (your question did not say melt Iodine, it said melt I2).Only gaseous iodine is composed of I2 molecules and as it is a gas it CAN NOT melt.

How much energy is needed to melt 25.4 grams of L's?
What are L's? And what's the heat capacity?

How much energy is gained by 3 grams of ice when it changes to water?
No energy is gained. On the contrary, energy is required to make ice melt.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
