Answer:
Mass = 7.6 g
Explanation:
Given data:
Volume of F₂ gas = 4.48 L
Standard Temperature = 273 K
Standard Pressure = 1 atm
Mass of gas = ?
Solution:
PV = nRT
P = pressure
V = Volume
n = number of moles
R = general gas constant
T = temperature
n = PV/RT
n = 1 atm×4.48 L / 0.0821 atm. L/ mol.K × 273 K
n = 4.48 atm. L / 22.4 atm. L/mol
n = 0.2 mol
Mass of F₂ gas :
Mass = number of moles × molar mass
Mass = 0.2 mol × 38 g/mol
Mass = 7.6 g
