Answer:
The gas was N₂
Explanation:
V = 3.6L
P = 2.0 atm
T = 24.0°C = 297K
R = 0.0821 L.atm/K.mol
m = 8.3g
M = molar mass = ?
Using ideal gas equation;
PV = nRT
n = no. Of moles = mass / molar mass
n = m/M
PV = m/M * RT
M = mRT / PV
M = (8.3*0.0821*297) / (2.0*3.6)
M = 28.10
Since X is a diatomic molecule
M = 28.10 / 2 = 14.05 g/mol
M = Nitrogen
X = N₂

The thermal energy needed to completely melt 9.60 mole of ice at 0.0 C is 57.8 Kj
Explanation
ice melt to form water
The molar heat of fusion for water is 6.02 Kj/mol
Thermal energy = moles x molar heat of fussion for water
=9.6 mol x6.02 kj/mol =57.8 Kj
