Answer:
Mass = 157.56 g
Explanation:
Given data:
Mass of Xe in gram = ?
Volume = 26.17 L
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Solution:
we will calculate the number of moles first.
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm ×26.17 L = n×0.0821 atm.L/ mol.K × 273.15 K
26.17 atm.L = n× 22.43 atm.L/ mol
n = 26.17 atm.L / 22.43 atm.L/ mol
n = 1.2 mol
Mass of Xe:
Mass = number of moles × molar mass
Mass = 1.2 mol × 131.3 g/mol
Mass = 157.56 g
