How do I find the specific latent heat of fusion of nitrogen?

[max1020]

When doing an experiment to find the specific latent heat of fusion of liquid nitrogen, you find that 100 kJ of heat must be removed to freeze 3.8kg of nitrogen at its freezing point. What value will you get for the specific latent heat of fusion of nitrogen?

Power=100kj
M=3.8kg
I don't know how to use these to find the value of the specific latent heat of fusion of nitrogen

 

[SteamKing]

Power is not measured in kJ.

You know how much heat must be removed from 3.8 kg of LN2 in order to freeze it. What is the definition of 'specific latent heat of fusion'? Apply the definition of this term to the data you were given.

This the definition mean the amount of heat energy that you have to put into a substance that will make a change of state but not raise the temperture of it.
But I don't know how to apply it to the question

It is not just the amount of heat. It's the amount of heat per unit mass. When you see the word "specific" in this type of context, it means "per unit mass."
