At 1 atm, nitrogen (n₂) molecules become a liquid below 77 k. thus the vapor pressure of liquid nitrogen is 1 atm at 77 k. use this information to estimate the binding energy of a nitrogen molecule within the liquid.
note: you may assume that the equilibrium condition for this system is ng/v=nte−δ/ktng/v=nte−δ/kt, with nt=nt= 1.93 × 10³¹ m⁻³, and that the nitrogen gas is ideal.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
