Answer:
n = 2 mol
Step-by-step explanation:
Given data:
Number of moles of water vapors = ?
Volume of water vapors = 44.8 L
Temperature = 273 K
Pressure = 1 atm
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
by putting values,
1 atm × 44.8 L = n×0.0821 atm.L/ mol.K × 273 K
44.8 L. atm = n×22.4 atm.L/ mol
n = 44.8 L. atm /22.4 atm.L/ mol
n = 2 mol
