Answer :
Answer:
The answer to your question is P = 17.73 atm
Explanation:
V = 250 ml = 0.25 liters (L)
mass = 3.4 g
Temperature = 45°C = 45 + 273 = 318°K
Pressure = ?
R = 0.082 atm L / mol°K
Atomic mass Ne = 20.18 g
Process
1.- Calcule moles of Neon
20.18 g of Ne ------------------ 1 mol
3.4 g of Ne ------------------- x
x = (3.4 x 1)/20.18
x = 0.17 moles of Neon
2.- Find pressure
Ideal gases formula PV = nRT
[tex]P = \frac{nRT}{V}[/tex]
[tex]P = \frac{(0.17)(0.082)(318)}{0.25}[/tex]
[tex]P = \frac{4.433}{0.25}[/tex]
P = 17.73 atm
