Answer:
Explanation:
We are given that
Diffusion coefficient,
Thickness of membrane,
Area,
Concentration differences,
We have to find the flow rate of sodium ions.
Flow rate,
Using the formula
Volume in liters:
139 cm³ / 1000 = 0.139 L
molar mass Argon = 39.95 g/mol
1 mole -------- 22.4 L ( at STP )
? mole ------- 0.139 L
moles of argon :
0.139 * 1 / 22.4 = 0.00620 moles
Mass of argon :
0.00620 * 39.95 = 0.24769 g
hope this helps!
