A 25 g Ice Cube at its melting point is in an insulated container with liquid nitrogen. How much nitrogen is vaporized when the boiling point of 77 K and has a heat of vaporization of 200 kJ / kg? Suppose, for simplicity, that is the specific heat of ice is a constant and equal to its value near the melting point.

In kg

Thanks for the help!
