Answer:
P = 34.95 atm
Explanation:
Given data:
Volume of tank = 150 L
Mass of neon gas = 5.0 Kg ( 5×1000= 5000 g)
Temperature = 258 K
Pressure exist = ?
Solution:
Number of moles of neon gas:
Number of moles of neon gas = mass/molar mass
Number of moles of neon gas = 5000 g/ 20.2 g/mol
Number of moles of neon gas = 247.5 mol
PV = nRT
P = nRT/V
P = 247.5 mol × 0.0821 atm. L. k⁻¹. mol⁻¹ × 258 K / 150 L
P = 5242.5 atm. L /150 L
P = 34.95 atm
