How much liquid nitrogen boils away as the washer cools

Reference no: EM13660768

In a physics lab, a student accidentally drops a 21.0-g brass washer into an open Dewar of liquid nitrogen at 77.2 K. How much liquid nitrogen boils away as the washer cools from 291 K to 77.2 K? The latent heat of vaporization for nitrogen is 199.1 kJ/kg.
