Answer:
T = 552.632 K
Explanation:
Mass of nitrogen = 25.7 g
Volume = 50 L
Pressure = 640 mmHg (640/760 = 0.84 atm)
Temperature = ?
Solution:
Number of moles of nitrogen:
Number of moles = 25.7 g/ 28 g/mol
Number of moles = 0.92 mol
Temperature:
PV = nRT
T = PV/ nR
T = 0.84 atm × 50 L /0.92 mol × 0.0821 L. K⁻¹. mol⁻¹. atm
T = 42 atm. L / 0.076 L. K⁻¹.atm
T = 552.632 K
